Heat Treatment 440a Stainless Steel Better Rust Resistance - China

440A stainless steel is a heat-treatable reinforced stainless steel, and its hardness after heat treatment can reach about HRC50 - Highest hardness.

Used for nozzles and bearings.

440F: It is a steel type that improves the easy cutting performance of 440C steel.

Usually the hardness of 440A/B on the cutting tool is 55~57HRC, and the hardness of 440C is 58HRC.

These three models of 440 stainless steel have covered the entire average hardness range of knife steel, from table knives to sturdy utility knives.

The advantage of 440A is that it has good rust resistance and is suitable for making diving knives.

The hardness is affected by the carbon content, and the hardness is about 56 - It can only be said to be just right for making daily knives.
