The difference between high carbon steel and high carbon steel, which is better, high carbon steel o

High manganese steel belongs to spring steel, so the toughness is significantly greater than that of high carbon steel, while the hardness is just the opposite.

Contradictory unity of hardness and elasticity.

The maximum hardness of high-manganese steel is generally HRC56 (long knife is enough), and high-carbon steel can be HRC62 abroad (58-60 in China).

As for patterned steel, it is a composite steel itself, so the characteristics depend entirely on the properties of several metal elements that make it up.

But toughness is better than any of these elemental metals is a certainty.

However, ninety percent of the domestic pattern steel is made by ordinary stainless steel electroerosion treatment, which is simply a fake.

Beware of being fooled!

From the literal meaning, it can be seen that the composition of the two alloys is different in the first place.

High-carbon steel has high hardness, and high-manganese steel (spring steel) has low hardness, but the toughness is much better than that of high-carbon steel, and the possibility of high-carbon steel breaking when subjected to the same violent slashing is great.

High manganese steel refers to alloy steel with a manganese content of more than 10%, which is a kind of anti-wear steel specially used in heavy industry, and its application fields include quarrying, mining, excavation, coal industry, foundry and steel industry.

High-carbon steel, commonly known as tool steel, is mainly used to make cutting tools, etc. The carbon content is from to. It is characterized by being hard and brittle, and can be quenched, hammered, crowbars, etc., made of steel with carbon content; Cutting tools such as drills, taps, reamers, etc. are made of carbon content.

to the manufacture of steel.

High carbon steel and high manganese steel which is better than that good, the use of the two is not the first is to participate in the composition of the alloy is different, high carbon steel hardness, high manganese steel (spring steel) hardness is low, but the toughness is much better than high carbon steel, the possibility of high carbon steel breaking when subjected to the same violent slash is great, high manganese steel refers to alloy steel with a manganese content of more than 10%, is a kind of anti-wear steel designed for heavy industry, applications include quarrying, mining, excavation, coal industry, foundry and steel industry. High-carbon steel, commonly known as tool steel, is mainly used to make cutting tools, etc. The carbon content is from to.

It is characterized by being hard and brittle, and can be quenched, hammered, crowbars, etc., made of steel with carbon content; Cutting tools such as drills, taps, reamers, etc. are made of steel with a carbon content.

The main charges are high-quality carbon steel (or ingots), high-carbon ferromanganese, medium-carbon ferromanganese, high-carbon ferrochrome and high-manganese steel returns. It is important to note that it is believed that as long as the chemical composition is appropriate, more return material can be used. This realization is harmful.

This is the reason why the quality of some factories is poor.

High Carbon Steel Advantages:

1. After heat treatment, high hardness (HRC60-65) and good wear resistance can be obtained.

2. The hardness is moderate in the annealed state and has good machinability.

3. Raw materials are easy to obtain and production costs are low.

The disadvantages of high-carbon steel are:

1. Poor hot hardness, when the working temperature of the tool is greater than 200, its hardness and wear resistance drop sharply.

2. Low hardenability. The diameter of the complete quenching during water quenching is generally only 15-18mm; The maximum diameter or thickness of the oil quenching is only about 6mm, and it is easy to deform and crack.

The hardness and strength of high-carbon steel mainly depend on the amount of dissolved carbon in the steel, and increase with the increase of the amount of dissolved carbon. When the amount of solid solution carbon is exceeded, the hardness does not increase after quenching, but the amount of excess carbide increases, the wear resistance of the steel increases slightly, and the plasticity, toughness and elasticity decrease. For this reason, different steel grades are often selected according to the use conditions and the matching of the strength and toughness of the steel.

For example, to make springs or spring parts that don't apply much force, you can choose 65 steel with a lower carbon content.

Generally, high-carbon steel can be produced by electric furnaces, open-hearth furnaces, and oxygen converters. When high quality or special quality is required, electric furnace smelting and vacuum self-consumption or electroslag remelting can be used. When smelting, the chemical composition, especially the content of sulfur and phosphorus, is strictly controlled.

To reduce segregation and improve isotropic properties, ingots can be annealed by high-temperature diffusion (especially important for tool steels). During hot processing, the stop forging (rolling) temperature of the eutectic steel is required to be low (about 800), and the precipitation of coarse network carbides should be avoided after forging and rolling, and slow cooling should be paid attention to below 700 to prevent cracks caused by thermal stress. Surface decarburization is prevented during heat treatment or heat working (especially important for spring steels).

There should be sufficient compression ratio during hot working to ensure the quality and use performance of the steel.

Manganese steel is a little better. The tool needs a certain toughness, and high-carbon steel has good rigidity but poor toughness and is easy to break. 65 manganese steel has slightly better toughness.

Manganese steel is a kind of steel, which is a high-strength manganese-resistant steel, which is mainly used to withstand severe working conditions such as impact, extrusion, material wear, etc., and is a typical wear-resistant steel, and the as-cast structure is austenite plus carbide. After water quenching treatment at about 1000°C, the microstructure is transformed into a single austenite or austenite with a small amount of carbide.

High Carbon Steel Introduction:

After being properly heat treated or cold drawn and hardened, high-carbon steel has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), and the cutting performance is acceptable, but the welding performance and cold plastic deformation ability are poor. Due to the high carbon content, it is easy to produce cracks during water quenching, so double-liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross-section parts.

This type of steel is generally used after quenching by medium temperature tempering or normalizing or in a surface quenching state. It is mainly used in the manufacture of springs and wear-resistant parts. Carbon tool steel is a high-carbon steel that basically does not add alloying elements, and it is also a steel grade with low cost, good cold and hot workability and a wide range of use in tool steel.

It has a carbon content of one and is a steel that is specially used to make tools. High carbon steel density.

Manganese steel and carbon steel are better than manganese steel.

Strictly speaking, it should be judged according to the use of different environments, but for the cognition of knives, most friends should first think of knives in the family. Then because the knives used in the family are aimed at some foods, and they prefer to have a longer service life of the knives, the effect will be better if they choose knives made of manganese steel materials.

Looking at the knife products sold on the market now, you will find that most of them are made of manganese steel, and many kitchen knives made in Germany are very sharp after multiple forgings in manganese steel, and the toughness is also very good, which can meet any food at home. The most important thing is that you won't have a problem using it for 10 years.

If it is an industrial choice, it is the opposite. For example, the tools used in industrial production must abandon toughness, because the more flexible the tool, the more likely it is to be blunt when used. Even knives made of carbon steel, which frequently crack, are better than knives made of manganese steel.

Manganese steel

Manganese steel is a kind of high-strength steel, mainly used to withstand impact, extrusion, material wear and other harsh working conditions, the failure form is mainly wear and tear, partial fracture, deformation, suitable for engine lower guard. Cast wear-resistant and wear-resistant steels are mainly austenitic manganese steels, low-alloy steels with appropriate heat treatment also have good results, and graphite steels are used to lubricate friction conditions.

Depending on what occasion it is used and how cost-effective, it cannot be said in general.

1. Carbon steel material: iron-carbon alloy with carbon content.

2. Manganese steel: a high-strength steel.

Second, the characteristics are different.

1. Carbon steel material characteristics:

1) It contains small amounts of silicon, manganese, sulfur, and phosphorus.

2) The higher the carbon content in carbon steel, the higher the hardness and strength, and the lower the plasticity.

2. Characteristics of manganese steel: under strong impact and extrusion conditions, the surface hardens rapidly, maintaining the good toughness and plasticity of the core austenite, and the hardened layer has good wear resistance. This is unmatched by other materials.

However, the wear resistance of high manganese steels only shows its superiority when there are sufficient work hardening conditions, and in other cases it is very poor.

Question: Which is better, carbon steel guard plate and manganese steel guard plate?

Manganese steel, also known as manganese alloy steel, is a high-strength steel, mainly used to withstand severe working conditions such as impact, extrusion, material wear, etc., and the failure form is mainly wear and tear, partial fracture and deformation, and is now generally applicable to the engine lower guard.

Cast wear-resistant steel and wear-resistant steel in austenite.

Manganese steel is the mainstay, and low-alloy steel with proper heat treatment under certain conditions also has a good effect, and graphite steel is used for lubricating friction conditions.

Wear-resistant high manganese steel.

It is especially suitable for impact abrasive wear and high-stress crushing abrasive wear conditions, and is often used in the manufacture of ball mill lining, hammer crusher hammer head, jaw crusher jaw plate, cone crusher Shouxiao rolling mortar wall, crushing wall, excavator bucket teeth, bucket wall, railway turnout, tractor and tank track shoes and other impact-resistant and wear-resistant castings.

Features of high manganese steel:

The most important feature of high manganese steel is that under the conditions of strong impact and extrusion, the surface layer quickly undergoes work hardening, so that it still maintains good austenite toughness and plasticity in the core, and the hardened layer has good wear resistance.

This is beyond the reach of other materials. However, the wear resistance of high manganese steel only shows its superiority when it is sufficient to form work hardening, and in other cases it is poor.

The typical Mn17 wear-resistant high manganese steel is based on the Mn13 steel to increase the amount of manganese, improve the stability of austenite, prevent the precipitation of carbides, and then improve the strength and plasticity of the steel, and improve the work hardening ability and wear resistance of the steel. For example, the life of ZGMN18 railway forks used in the north is 20% and 25% longer than that of ZGMN13.

According to the needs of the work, manganese steel belongs to alloy steel, and carbon steel belongs to carbon steel.

It's not good or bad, because the uses are different.

Look** use. Different materials have different properties.

1. The content is different: high manganese steel.

It refers to alloy steel with a manganese content of more than 10%.

Generally, the content of manganese in steel is greater than 7%, and the material dominated by manganese element belongs to high manganese steel. There are still very few rolled high-manganese steel plates, which are basically cast. The alloy steel content of manganese steel is different, and the content is about 3.

2. Different hardness: high manganese steel (spring steel.

The hardness is low, but the toughness is much better than that of manganese steel, and when it withstands the same violent slash, the possibility of manganese steel breaking is very great.

3. Different uses: when the high manganese steel is heated to light orange, it becomes very soft and easy to carry out various processing. At present, people use manganese steel in large quantities to make steel mills, ball bearings, and bulldozers.

Buckets and other components that are often worn with excavators. Manganese steel is mainly used to withstand severe working conditions such as impact, extrusion, and material wear, and the failure form is mainly wear and consumption, and is now generally applicable to the engine lower guard.
