Which is better, bearing steel or carbon steel, and which is better, carbon steel or steel

First, in terms of the length of service life. There is a big difference in their service life time, the service life of bearing steel is long, and many garbage bearings are carbon steel bearings, mainly because the hardness and wear resistance are not as good as bearing steel bearings.

Second, in terms of wear resistance. Mild steel is only quenched on the surface carburized surface layer and is not fully hardened. Many low-grade carbon steel bearings on the market are not hardened at all, and the wear resistance is extremely poor.

Third, in terms of process and use effect. The use of bearings is related to the use of the environment, not that the carbon steel bearing is not good, it depends on which machinery is used, because some do not need high-grade, the use of carbon steel around the bearing is suitable. Of course, Luogang's is better, but the cost is much higher, and the most commonly used bearing steel is GCR15.

Fourth, in terms of bearing materials and performance. For example, bearing rings and rolling elements are subjected to high contact pressures repeatedly, and rolling contact accompanied by slippage is carried out while maintaining high-precision rotation. Therefore, whether the material and performance of the bearing ring, rolling element and cage meet the following requirements:

High elastic limit; High rolling fatigue strength; It should have high hardness; Good abrasion resistance; Good toughness against shock loads; Good dimensional stability. In addition, it is necessary to have good processability. It has been confirmed that the bearing steel has the above required properties, but the carbon steel bearing cannot be guaranteed.

Fifth, it is not that the advantages of carbon steel bearings are nowhere to be used without bearing steel, which depends on the use of **. Carbon steel bearings are noisy, have a particularly short life, and are particularly stressed by them, but they can be used in places where the hardness and ultimate speed are relatively small.

The performance of the bearing steel is better, and this is the main difference. Carbon steel is almost.

Carbon steel: high carbon content, high hardness, small toughness, mainly used to make knives Machine tool bearing steel: also known as ductile steel Carbon content % Both toughness and hardness The main difference between a wide range of steel is that the carbon content is different, the carbon content of carbon steel is high, the toughness is also small, and the carbon content of bearing steel is different from the content of chemical element carbon.

It's up to you for what you're for.

But look at the quality must be the bearing steel.

But some parts can be heat treated with carbon steel.

You don't have to use a material as expensive as bearing steel.

There is no comparison of the conditions is meaningless, the ruler is short, the inch is long. The performance of bearing steel is good in many aspects, but it is not absolute.

It's best to use bearing steel, but there are good and bad things here, and if you can make a bearing steel that meets the SKF-3 standard, the standard is the best.

In the bearing industry, the bearing steel used in the bearing must be the best!

On quality. Bearing steel, of course.

The worst quality of bearing steel can measure the level of steelmaking in a country.

Both carbon steel and steel are good.

Carbon steel is more wear-resistant and corrosion-resistant, but it is lighter and less strong than steel. Steel is stronger and more durable, but it is more susceptible to corrosion.

Ordinary carbon steel is the abbreviation of ordinary carbon structural steel. The carbon content is less than that, and less than is the most commonly used. It is a mild steel, and each metal grade indicates the lowest yield point of the steel grade when the thickness is less than 16mm.

Compared to high-quality carbon steel, there are wider restrictions on carbon content, performance range, and phosphorus, sulfur, and other residual element content. According to the guarantee conditions of delivery, China and some countries divide ordinary carbon steel into three categories: Class A steel (Class A steel), which only guarantees mechanical properties and does not guarantee chemical composition, and Class B steel (Class B steel), which only guarantees chemical composition and does not guarantee mechanical properties.

Special steel (C steel) not only guarantees the chemical composition, but also ensures the mechanical properties. Special steels are often used in the manufacture of more important structural parts.

Use. 1. Low carbon steel is used in the production of various industries.

2. Consumers or all walks of life can find low carbon steel in imperial and metric sizes that meet different requirements.

3. Steel with lower carbon content has higher crack resistance, swims and maintains ductility that is not affected by temperature.

4. Steel with relatively low carbon content is easy to crack or break under pressure, but low carbon steel will only bend and not crack.

5. Mild steel contains about 40 points of carbon.

6. The carbon content of each represents a point.

7. Because the low carbon steel contains inseparable components, it can form different plates, sheets and tubes. <>

Summary. Dear, hello I am glad to serve you, carbon steel is actually iron, there is no difference between the two, and it is impossible to compare the material. Iron is a relative term for other types of metal, and is used to distinguish copper, aluminum, lead, etc.

In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity. Previously, iron was divided into pig iron and wrought iron, pig iron was called iron, and wrought iron was called steel.

Carbon steel is a classification of steel, which divides steel into two categories: carbon steel and alloy steel.

Dear, hello I am glad to serve you, carbon steel is actually iron, there is no difference between the two, and it is impossible to compare the material. Tie Ming is the name given to other types of copper, aluminum, lead, etc. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus.

Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity. Previously, iron was divided into pig iron and wrought iron, pig iron was called iron, and wrought iron was called steel. Carbon steel is a classification of steel, which divides steel into two categories: carbon steel and alloy steel.

Carbon steel is a silver alloy with iron-carbon coded silver containing and covering carbon. It is also called Chiyan carbon steel. Generally, it also contains small amounts of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.

Classification (1) According to the use, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel, and carbon structural steel is divided into two types: engineering construction steel and machine manufacturing structure car starving steel; (2) According to the smelting method, it can be divided into open-hearth steel and closed converter steel; (3) According to the deoxidation method, it can be divided into boiling steel (F), calm steel (Z), semi-calm steel (B) and special calm steel (TZ); (4) According to the carbon content, carbon steel can be divided into low carbon steel (WC, medium carbon steel) (and limb medium and high carbon steel (WC>; 5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and high-grade high-quality steel (lower phosphorus and sulfur content) and special high-quality steel.

Blade steel and bearing steel are both common high-quality steels, each with its own characteristics and scope of application.

Fenggang is an alloy steel with high strength, high toughness and high wear resistance, which is mainly used to make tool steels such as high-speed cutting tools, dies and stamping dies. Fenggang has excellent hardness and wear resistance, as well as good toughness and toughness, so it is not easy to break and wear in the process of cutting and stamping, and has a long service life. The main components of Fenggang are carbon, chromium, vanadium, molybdenum and other elements, and its specific composition and performance indicators vary according to different uses and requirements.

Bearing steel is a kind of special steel socks, which is mainly used to manufacture high-precision parts such as bearings. Bearing steel has the characteristics of excellent wear resistance, corrosion resistance and high strength, and at the same time, Haosou has good hardness and toughness, which can meet the requirements of high-precision parts for strength and precision. The main components of bearing steel are carbon, chromium, molybdenum and other elements, and their specific composition and performance indicators are also different according to different uses and requirements.

Therefore, both front steel and bearing steel are high-quality steel posture materials, but their scope of application is different, and they need to be selected according to specific use requirements. If you need to manufacture tool steels such as high-speed cutting tools, dies, and stamping dies, then Fenggang is a better choice; If you need to manufacture high-precision components such as bearings, bearing steel is a better choice.

Dear, hello, I'm glad to answer for you, which is better for the load-bearing of stainless steel or carbon steel Carbon steel is better than stainless steel due to the difference in mechanical properties between carbon steel and stainless steel, so it is difficult to generalize. Stainless steel is generally more malleable than carbon steel, mainly because they have more nickel content. However, there are also stainless steels that are very brittle, such as martensitic stainless steel.

If there is enough carbon content in carbon steel, such as carbon content, then carbon steel is easier to heat treat than austenitic stainless steel.

High-carbon steel. If the carbon content is greater than that, it becomes a high-carbon steel, while the carbon content of the bearing steel is about 1%.

Bearing steel belongs to high-carbon steel, the most commonly used material is GCR15 bearing steel, also known as high-carbon chromium steel, with a carbon content of about 1% C and a chromium content of CR. Bearing steel is divided into six categories: high carbon chromium bearing steel, chromium-free bearing steel, carburizing bearing steel, stainless bearing steel, medium and high temperature bearing steel and anti-magnetic bearing steel.

High carbon chromium bearing steel GCR15 is the world's largest production of bearing steel, carbon WC is about 1%, chromium content WCR is about, from 1901 birth to more than 100 years, the main components have not changed, with the progress of science and technology, research work continues, product quality continues to improve, accounting for more than 80% of the world's total bearing steel production. So much so that if there is no special description of bearing steel, it refers to GCR15.

China has produced high-carbon chromium stainless bearing steel, the main steel grade is 9cr18; Carburized bearing steel, the main steel grade is G20CRMO; Chromium bearing steel, the main steel grade is GCR15.

Bearing steel, not belonging to carbon steel, it is a kind of steel with its own grade, domestic GCR15 steel, bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel grades in all steel production! Wanwang bearing.

Bearing steel is divided into four categories: fully hardened bearing steel, surface hardening bearing steel, stainless bearing steel, high temperature bearing steel and other four categories of a total of 17 steel grades.

Bearing steel is a steel grade used in the manufacture of balls, rollers and sleeves for rolling bearings, and can also be used to make precision measuring tools, cold stamping dies, machine tool lead screws and precision couples for diesel engine oil pumps.

I'm familiar with GCR15.

GCR15 steel is a high-carbon chromium bearing steel with less alloy content, good performance, and the most widely used. After quenching and tempering, it has high and uniform hardness, good wear resistance and high contact fatigue performance.

The bearing steel used in the bearing of Jinan Haokun Machinery Technology is very good, and the bearing is very good, and the life is also long.

What material is good for bearing steel, the quality of the bearing is largely determined by the bearing steel, because the bearing steel is used to manufacture the rolling elements and rings of rolling bearings, since it accounts for two parts of the bearing structure, it shows that the choice of bearing steel is very important, so what material of bearing steel is good, it is a topic of concern. Because the bearing has the characteristics of long life, high precision, high rigidity, low noise, etc., the corresponding bearing steel selection must also have these characteristics, it should have high hardness, uniform hardness, high elastic limit, corrosion resistance and other properties, so that the bearing steel made of the bearing is of better quality. What material is good for bearing steel, and it is necessary to pay great attention to the requirements of bearing steel to achieve good performance in production, and each link must be strictly controlled.

Most stainless steel bearings are used in corrosive environments, but they are not completely rust-free, but the rust-resistant time is better than that of bearing steel. Oh, personal opinion, I don't know if it's right or wrong.

Stainless steel is a high-chromium (generally 12% 30%) alloy steel that presents a blunt state, corrosion-resistant and rust-free in the atmosphere and corrosive media such as acids, alkalis, and salts.

Generally speaking, the bearing steel is GCR15 or GCR15SIMN, and its CR content is %, so it is not stainless steel.

The CR of the bearing steel is to improve the hardenability, not to prevent rust.

Bearing steel is a high-carbon steel and stainless steel is different.
