c material is used to make knives. SKD11 is a cold work die steel material with high wear resistance and toughness.
The domestic is called CR12MO1V1, and the United States is called DSKD11 high-carbon and high-chromium alloy tool steel and vacuum degassing refined steel, which is pure steel and has good hardenability with good hardenability and small quenching deformation.
The difference between C material and SKD11 is as follows: 440C and SKD11 are hard, SKD-11 has good high temperature strength and toughness, good wear resistance, easy to cut, SKD11 is a cold die with high strength, toughness and heat resistance balance.
3. The price is not the same, and it is not the same country's brand, H13 is the American brand, SKD61 is the Japanese brand, and H13 is the same as the hot work die steel; SKD11 and CR12MOV are cold work die steels, 11 are Japanese, and CR12 are Chinese; 40cr is generally used for shaft parts, and I have never seen it used as a mold.
C and SKD11 are hard, SKD-11 has good high temperature strength and toughness, good wear resistance, easy to cut, SKD11 is a cold die with high strength, toughness and heat resistance balance.
Difference Between A, 440B, 440C and 440F There are 4 models of SUS440 series martensitic stainless steel, which are SUS440A, SUS440B, SUS440C, and SUS440F.
c, is the American steel grade. In fact, the carbon content is higher than that of 9Cr18MoV, close to 9Cr18Mo, or even higher. If it is imported 440C stainless steel, if it is used as a tool, if the heat treatment is done properly, it should be able to achieve HRC59-6 and the wear resistance is higher than that of 9CR18MOV. However, the performance of domestic 9CR18MO is significantly inferior to that of 440C stainless steel.
1. ATS-34 is also a high-carbon steel, its hardness can be made to HRC59-61, the grinding degree is very good, even if the hardness is so high, it still has enough toughness, and the rust resistance is not as good as the 440 series, which is one of the best blade steels at present.
2. Due to heat treatment, the blade retention is not as good as ATS34 steel, but the toughness is better than ATS34 steel, and the toughness of AUS10 is comparable to that of 440C steel, but the carbon content is less, so it is less easy to rust (containing chromium 13 15%) and the toughness is better.
Good, because it's tougher than d2. 440C material is better, 440C is martensitic stainless steel 9Cr18, the hardness is slightly lower, but the rust resistance is good. 440C steel is a martensitic type of stainless steel.
It has strong rust resistance and is a high-quality stainless steel. Scope of application: It is mainly used to manufacture bearing parts that work in corrosive environments and non-lubricated strong oxidation atmospheres.
4. The characteristic of austenite is that it has very good plasticity, so to forge steel, it must first be heated to the temperature at which austenite is formed. However, the body-centered cubic lattice, the gap radius is relatively small, and the carbon atoms cannot be accommodated, and the carbon atoms can only exist if there are defects in the structure.
5. Is it good to use 420J2 or 440HC for outdoor knives Thank you Of course, 440 steel is good, with high hardness, and knives are generally used! 420J2 is softer The general kitchen knife uses 440 with high hardness. 420 toughness is high, and if it is used normally, it is recommended that about 700 is moderately soft and hard, and 1095 high-carbon steel can also be used to make one.
HRC, 440B hardness 55HRC, 440C hardness 57HRC. Surely, you can say about this difference? Often? , but what is the hardness of the steel? What does the field play? What matters? So 440c stainless steel became now? It is the most prevalent material in the market.
