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).

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.

Otai Steel is one of professional supplier of 440c stainless steel supplier with reliable quality. The following is our supply range and 440c steel chemical composition and other properties.

Features & Benefits

  • After appropriate heat treatment, 440C stainless steel can achieve a high level of hardness, typically between 58-60 HRC, making it suitable for applications requiring high hardness.
  • Due to its high carbon content and excellent heat treatment properties, 440C stainless steel exhibits outstanding wear resistance, making it suitable for various applications such as cutting tools, bearings, etc.
  • 440C stainless steel can be effectively machined under appropriate conditions to meet various component requirements. However, due to its high hardness and strength, machining may be relatively challenging and requires suitable machining processes and tools.
  • 440C stainless steel demonstrates good high-temperature stability, maintaining its hardness and wear resistance under elevated temperature conditions, making it suitable for applications in high-temperature environments.
  • The mechanical properties of 440C stainless steel can be adjusted through heat treatment, such as hardness, strength, and toughness, to meet specific application requirements.
