  440C stainless steel sheet has good high temperature dimensional stability, which makes it can also be used as corrosion resistant high temperature bearing steel. In addition, it can also be used for manufacturing high-quality knives, such as surgical scalpel, scissors, nozzles, bearings, etc. The ability of 440C stainless steel sheet to bear the dynamic load is low.

  Hardness: annealing, less than 269HB; quenching and tempering, more than 633HV

  Mechanical properties: internal stress (250 N/mm2) tensile strength (560 N/mm2) EL (18%) HB (250)

  Heat treatment process
