1: 440C Stainless steel introduction

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).

AISI 440C steel is characterized by good corrosion resistance in mild domestic and industrial environments, including fresh water, organic materials, mild acids, various petroleum products, coupled with extreme high strength, hardness and wear resistance when in the hardened and tempered condition. Grade 440C stainless steel is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Small AISI 440C steel sections can be air cooled and quite large sections oil quenched for maximum through hardness.

Application

ASTM 440C steel has been widely used for parts requiring a combination of excellent wear resistance, plus reasonable corrosion resistance.

ASTM Stainless Steel 440C is used typically in the following applications:

  • Cutlery
  • Ball bearings and races
  • Molds and dies
  • High quality knife blades
  • Valve components, pump parts,
  • Measuring instruments, Surgical instruments
  • Wear-resistant textile components.

6: Delivery condition
For hot forged bar, usually the delivery condition is hot forged, annealed/QT rough turned/Black surface.
For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
