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. 440A/B/C stainless steel round bar - Chanson Metals Co 440B stainless steel has higher hardness and toughness than 440C steel. 440B stainless steel is used for cutting tools, measuring tools, bearings and valves. Suitable for bayonet blade. 440C is a martensitic stainless steel with higher carbon content than 3Cr13 steel, so its strength and hardness are higher than 3Cr13 steel.

What is 440C Stainless Steel? ASTM A276 standard grade 440c stainless steel is a high carbon martensitic stainless steel, which is generally supplied in the annealed condition with a maximum Brinell hardness of 269 (Rc29) or annealed and cold drawn with a maximum Brinell hardness of 285 (Rc31).
The American Iron and Steel Institute classifies it as 440C martensitic standard stainless steel. Most modern knifemakers simply call it 440C. 440A:this is a hardenable stainless steel alloy, hardenable to a higher hardness than 420 series stainless steels (which are only hardenable to 52 HRC!). 440A has good corrosion resistance, and is used
