What is 4Cr14?
4Cr14 stainless steel’s biggest feature is corrosion resistance, toughness is more than hardness is not enough, usually only used to do stainless steel containers or kitchen utensils, and can be stamping molding, but it does not belong to the edge of the steel!
What is 3Cr13?
3Cr13 American Standard is 420J2 stainless steel, belongs to the low-grade cutting edge steel, in addition to excellent rust resistance, other indicators are very general, mainly used to make kitchen knives often in contact with water, the hardness of HRC53 or so.
What Kind Of Steel Is 4Cr13Mov?
4Cr14Mov is a martensitic stainless steel.
Hardenable martensitic stainless steel, each material has its own different heat treatment hardness and corrosion resistance. Products are widely used in the production of kitchen knives, butcher knives, fishing and hunting knives, industrial knives, scissors, ice skating knives, garden shears military knives, etc., more sharpness and corrosion resistance requirements of razors, beauty scissors, and so on. Commonly used steel: 20Cr13, 30Cr13, 40Cr13, 4Cr14Mov5Cr15MoV, 6Cr14, 7Cr17MoV, 8Cr17MoV, 9Cr18MoV, etc..
5Cr15MOV,6Cr14,6Cr14MOV,7Cr17MOV,8Cr14MOV,8Cr17MOV,9Cr13MOV,9Cr14MOV,9Cr18MO,9Cr18MOV, D2, SK2, SK5, etc., are produced by forging process of large ingots of 1.5~8 tons, which are forged into forging grudge and then rolled into steel strips and bars.
Through an advanced forging process and reasonable forging ratio, we can achieve the effect of refining grain, changing carbide morphology, removing deflection, increasing density, and so on. Make the internal organization of steel, and carbide distribution more uniform. Through a reasonable heat treatment process, the steel has the best mechanical properties.
What Kind Of Steel Is 4Cr14Ni14W2Mo?
4Cr14Ni14W2Mo is a hot work mold steel
4Cr14Ni14W2Mo belongs to the national standard valve steel, the implementation of standards: GB/T 1221-2007
4Cr14Ni14W2Mo has high-temperature strength and heat resistance, commonly used in the manufacture of engine intake and exhaust port valves, as well as steam and gas piping, can also be used to manufacture titanium alloy Creep forming molds, strong corrosive glass forming molds and die casting used core molds.
