Question:

Can 440 stainless steel be used as a knife?

Can 440 stainless steel be used as a knife?

Answer:

440 is martensitic stainless steel, equivalent to the domestic 11Cr17. Because of the high carbon content, the content of 0.95-1.2% is 16-18%, and the content of Cr is high enough to harden. The hardness is up to HRC58.Quenching temperature is 1010-1070, oil cold. Tempering 100-180 quick cooling.
Imported stainless steel 440C has the highest hardness in all stainless steel and heat resistant steel. For nozzles and bearings,.440F: is a type of steel that improves the easy to cut performance of 440C steel. For automatic lathes. Martensitic stainless steel and alloy steel has the same characteristics of hardening by quenching, so you can get a wide range of different mechanical properties by selecting the grade and heat treatment conditions. 440C stainless steel carbon C-1.2% steel rust resistant, is currently used in the tool on the market of high-grade batch of high-quality stainless steel, its strength and sharpness than ATS-34, chromium content up to 16-18%, is the second most commonly used stainless steel (after ATS-34), is the earliest by Cutler accepted stainless steel, and has been is very popular, especially in the freezing processes have been developed, this Strengthened Toughness of steel.
Because 440 is martensitic stainless steel, equivalent to the domestic 11Cr17. Because of the high carbon content, the content of 0.95-1.2% is 16-18%, and the content of Cr is high enough to harden. The hardness is up to HRC58. Quenching temperature is 1010-1070, oil cold. Tempering 100-180 quick cooling.
440 can be used as swords and other things.
