440C forged stainless steel round bar price, 440c stainless steel seamless tubing manufacture
Grade 440C stainless steel is used in the following applications:
▪ Gage blocks
▪ Cutlery
▪ Ball bearings and races
▪ Molds and dies
▪ Knives
▪ Valve components
▪ Measuring instruments
Grade 440C stainless steel is pre-heated at 760°C (1400°F). Temperature can be increased up to 1038-1204°C (1900-2200°F). It should not be heated below 927°C (1700°F). It is then slowly cooled at room temperature and fully annealed.
Grade 440C stainless steel is slightly cold workable using common practices.
Grade 440C stainless steel is annealed at 843-871°C (1550-1600°F) followed by slowly cooling in the furnace.
Grade 440C stainless steel can be tempered by soaking at 148°C (300°F).
Grade 440C stainless steel can be hardened by heating at 760°C (1400°F). Temperature can be increased up to 1010°C (1850°F) followed by cooling in air or oil.
