440Bthis is a hardenable stainless steel alloy, hardenable to a higher hardness than 440A. It has good corrosion resistance and is used in cutlery (economy), valves, and instrument bearings, where high wear is less important than high corrosion resistance.

440A Stainless Steel

440A is a high carbon martensitic stainless steel that is AOD melted. This alloy can be heat treated to extremely high hardnesses. It has slightly less carbon than 440B and 440C giving it better machinability but less hardness.

420 Vs. 440 Stainless Steel eHow

Tensile strength of 420. Tensile strength is a measure of the pulling force needed to break a material. The tensile strength of 420 grade stainless steel depends on its heat treatment temperature. Generally, the lower the heat treatment temperature, the higher the tensile strength.

440 or 1095? iKnife Collector

May 02, 2011 · 440A is not cutlery steel.. many manuf disagree with me. It's limited (.6~.75) carbon content also limits it's working hardness to a 51~52 Rc. 440B sees a greater use as cutlery steel.. it is cheap !!! But here again.. it's limited (.75~.95) C content puts it in the 55~56 range.
