How to distinguish between fierce steel and 50 fierce steel

50 steel is a medium-carbon structural steel, with good strength and toughness.

Steel has its code name. 40 steel refers to No. 40 steel, which is a type of steel that contains, a little silicon and a little manganese. The content can be checked above.

50% mainly contains carbon and 60% of steel, silicon and manganese are basically the same. Modern simple steel is basically based on the content of carbon, manganese and silicon, so many people call it 60 manganese, which is not special, but it is called manganese, and almost all steel contains some manganese. Carbon that contains more carbon is called high-carbon steel.

So 60 manganese, 70 manganese, t8, t10 and so on are all high carbon steels.

Steel contains a variety of different elements, which means that the potential of the steel is indicated.

In addition to the elements contained in steel, the most important thing is to exert the potential of these few elements by heat treatment. So what everyone should be entangled in is the master's heat treatment ability, not which steel is the best. The 60 manganese generally used in Longquan should be 60 silicon 2 manganese, but some people mix the 60 steel without silicon, but the elasticity of the steel with silicon () is better.

As for the extreme manganese steel.

It should refer to heat treatment. Now some merchants have repackaged 60 silicon 2 manganese from the new packaging, done some so-called high elasticity heat treatment, called a new name to make a selling point, although I can't be sure, but it is estimated that they are all the same, that is, the use of silicon general manganese steel, do a good point of heat treatment, to ensure that the elasticity is good. Extreme manganese steel is estimated to be one of these kinds of advertising!

If the price is not increased too much, there is a limit or high elasticity, or something that is super supernatural is fine.

Manganese steel is wear-resistant, but not sharp enough, the advantages are high strength, good toughness, high hardness can be obtained through heat treatment, and has certain anti-corrosion properties.

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. Cast wear-resistant steel and wear-resistant steel are mainly austenitic manganese steel, and the low-alloy steel with proper heat treatment under certain conditions also has a good effect, and graphite steel is used for lubricating friction conditions.

Manganese steel**: People use manganese steel in large quantities to make steel mills, ball bearings, bulldozers and excavator buckets and other often worn components, as well as rails, bridges, etc., due to the use of manganese steel as a structural material, very strong, and the material is less than other steel, the average square meter of roof only 45 kg of manganese steel. Taking rebar as an example, the average price on March 9 last year was 2,475 yuan tons, and on March 9 this year, it has risen to 3,852 yuan tons, a range of 35%.

The strength, hardness, elasticity and hardenability of 65mn steel plate are not as good as that of high-carbon steel, and it has a tendency to overheat sensitivity and tempering brittleness, and water quenching has a tendency to form cracks. The machinability of the annealed state is acceptable, the cold deformation plasticity is low, and the weldability is poor. Leaf springs with medium loads, coil springs and spring washers with diameters of 7-20 mm.

Spring rings. High wear resistance parts, such as grinding machine spindles, spring chucks, precision machine tool screws, cutters, collars on spiral roller bearings, railway rails, etc. Although the hardness of high-manganese steel (spring steel) is low, the toughness is much better than that of high-carbon steel, and high-carbon steel is easy to break when subjected to strong violent slashing, while manganese steel is not easy to break.

..The main disadvantage of manganese steel is that the hardness is relatively low.

Summary. Hello, two grades, suitable for the purpose. 30 manganese steel is a manganese alloy steel with carbon content, good comprehensive mechanical properties, can be used for general force steel, good turning and bending performance, but must be stored indoors, easy to rust.

65 manganese steel is a high-carbon manganese alloy steel, with high carbon content and high hardness, and is the steel of choice for knives, saw blades and tools, but the turning performance is poor, slightly higher than 30 manganese steel.

Hello, two grades, suitable for the purpose. 30 manganese steel is a manganese alloy steel with carbon content, good comprehensive mechanical properties, can be used for general celery car force steel, good turning, bending performance, but must be stored indoors, easy to rust. 65 manganese steel is a high-carbon manganese alloy steel, with high carbon content and high hardness, and is the steel of choice for knives, saws, and tools, but the turning performance is poor, slightly higher than 30 manganese steel.

I'm asking 65 steel, not 65 fierce steel.

65 steel is; Medium and high carbon spring steel 65 steel, medium and high carbon spring steel. The steel has high strength, hardness and elasticity after heat treatment or cold work hardening, low cold deformation plasticity, poor welding and clever jointing, generally using oil quenching, large cross-section parts are hardened by water quenching oil cooling or normalizing treatment. 65 steel is used in the manufacture of springs, spring coils, various washers, clutches, and shafts, rolls, eccentric shafts in general machinery, etc.

Overall, 65 steel is better.

The pattern steel is harder than the wheel manganese steel, the hardness is 60hrc, and the hardness of manganese steel is 50hrc.

The higher the hardness, the higher the anti-wear ability, but the brittleness is also about large, and the hardness does not exceed 60HRC. The hardness of knives is usually expressed by the Rockwell C scale (HRC), which is an extrusion test of an object with diamond, and the hardness is higher if the depth is shallow.

Toughness is the ability of a material to be impacted by much energy without breaking. There is no way to take hardness and toughness into account, the harder it is, the more brittle it is, and the tougher it is, the softer it is.

Resistant to abrasion. It is related to the use of knives. The more resistant it is to wear and tear, the longer the knife can be used and still remain sharp. However, when sharpening knives, the more resistant the knife is, the more difficult it is to sharpen. No matter what material, no matter how hard you are, it will be dull to use.

Hello, there is no comparison between the two, and the analogy is like which is harder, steamed bun or hanamaki is a truth. First of all, you need to know that "manganese steel" is named after the material of the steel. Patterned steel is named after the shape of the steel and the way it is processed.

Manganese steel, also known as tool steel, has good plasticity and is suitable for use in the tools we use. Not easy to break and crumble. Patterned steel is forged steel.

That is, it depends on what you want to do with them. It can be very hard, it can be very soft. It is determined according to the ratio of their own materials.

Manganese steel, also known as tool steel, has good plasticity and is suitable for use in the tools we use, and there is no comparison between the two.

Manganese steel is determined according to the proportion of its own material, for example, which is harder than steamed bread or flower rolls, which is a truth. Patterned steel is forged steel. Patterned steel is named after the shape of the steel and the way it is processed.

It can be very hard, it can be very soft. First of all, you need to know that "manganese steel" is named after the material of steel. Not easy to break and crumble.
