Stainless Steel 440C ( 1.4125 ) is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make SS440C particularly suited to such applications as ball bearings and valve parts.

  • Hardenable high-carbon chromium steels designed to provide stainless properties with maximum hardness
  • Have maximum hardness together with high strength and corrosion resistance in the hardened and stress relieved condition
  • Always used in the hardened or hardened and stress relieved conditions
  • None of the alloys has its full corrosion resistance either in the annealed or in the hardened and tempered condition
  • Wide applications where good corrosion resistance along with high hardness or abrasion resistance is required

Applications of stainless Steel 440C

  • Used in numerous applications in areas where a very hard and abrasion resistant stainless is called for
  • Applications include pivot pins, dental and surgical instruments, cutlery valve parts, ball bearings, nozzles, hardened steel balls and seats for oil well pumps, plus valve parts

Will 440C rust?

These stainless steels have good corrosion resistance in the hardened and stress relieved conditions. Hence, they should, usually, be used only in that condition. These steels are resistant to such conditions as fresh water, steam, crude oil, gasoline, perspiration, and alcohol.

IS 440C stainless steel good for knives?
440C is a high carbon martensitic stainless steel that belongs to the 440 steel series. … This steel is loved by both knife makers and knife users due to its really high corrosion resistance. It also takes and holds a great mirror-like finish longer and requires very minimal care.
What hardness is 440C stainless steel?
440C (UNS designation S44004) is a martensitic 400 series stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 56–58 HRC. It is a bearing steel, and used in rolling contact stainless bearings, e.g. ball bearings and roller bearings.

IS 440C stainless steel magnetic?

Type 440C Stainless Steel is widely used in antifriction bearings, in valves and in many other applications where high hardness and reasonable corrosion resistance is required. This material is much more resistant to abrasion and wear than others stainless steel. sus440c is strongly attracted by a magnetic field.
