What is Surgical Steel?
1.2601 steel is German high carbon, high chromium Lacite steel. The electric furnace and vacuum refining technology are used to reduce the C and Cr content in the chemical composition. In addition, Ti and Nb are added to make the carbides fine and uniform, and Mo is added to maintain wear resistance.
1.2601 steel
Right!
- 1.2601 steel is German high carbon, high chromium Lacite steel. The electric furnace and vacuum refining technology are used to reduce the C and Cr content in the chemical composition. In addition, Ti and Nb are added to make the carbides fine and uniform, and Mo is added to maintain wear resistance.
- The steel has a relatively low impurity content and cleanliness has improved. Its carbon content is much lower than that of Cr12 steel, and the addition of molybdenum and vanadium has significantly changed the hot workability, impact toughness and carbide distribution of the steel.
- The steel has a higher
- In annealed state, the hardness is 225HBS.
- China GB standard steel number Cr12mov, German DIN standard material number 1.2601, German DIN standard steel number X165crmov12, Japanese JIS standard steel number SKD11, Korean KS standard steel number STD11, Swedish SS standard steel number 2310, American AISI / SAE standard steel number D3 . British BS standard steel number BD2, BD2A, French NF standard steel number 2235Z160CDV12 [1]
- The temperature is 1050 ~ 850 ° C.
- It is widely used to produce cold work with large cross section, complex shape, high impact resistance, and high wear resistance.
