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. 440C Martensitic Stainless Steel Bar - Alloys440C is a high carbon straight chromium high hardenability martensitic stainless steel, 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).Characterised by good corrosion resistance in mild domestic and industrial environments, including fresh water, organic materials, mild acids
440C is a high carbon martensitic stainless steel that is AOD or AOD + ESR melted. It has slightly more carbon than 440A and 440B giving it the highest hardness of any martensitic stainless alloy. This grade has excellent wear resistance making it perfect as a bearing steel AISI SS 440 Stainless Steel 440C 440A 440B Material Typical forging temperature range for 440A, 440B and 440C stainless steel. 440A:925-1200 440B:925-1175 440C:925-1150 Hardening. 440 stainless steel can be hardened and tempered in the same manner as alloy steel.

Type 420 Stainless Steel, also known as surgical steel, is an often used high-carbon martensitic stainless steel. It is similar to Type 410, but has more strength and hardness. It can be hardened through heat treatment, which brings good ductility for metal fabricators as well as excellent polishability. It resists corrosion in fresh water, alkalis,  alloy uns s44000 440c stainless steel round pipeStainless Steel Grade 440C (UNS S44004) Welding. Grade 440C stainless steel is not welded because it can be easily air hardened. To weld this alloy, it should be preheated to 260°C (500°F) and post weld treated at 732-760°C (1350-1400°F) for 6 h followed by slowly cooling in the furnace to prevent cracking.
