440C

440C is a 400 series stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58–60 HRC. It is a bearing steel, and used in rolling contact stainless bearings, e.g. ball and roller bearings. It is also used to make knife blades. 440C can be oil quenched to achieve maximum hardness.

440C has the highest strength, hardness, and wear resistance of all the commonplace 440-series stainless alloys with high carbon content and moderate corrosion resistance.[1]

Composition[2]

gollark: If you're firecubez, then explain why you are NOT cubes OR on fire.
gollark: Yes, you're "firecubez"; this is true and not false, entirely.
gollark: `>>` is a special case of `>>=`, which encapsulates all the real-world-passing stuff in a way which also happens to generalize nicely to everything else, thus monads.
gollark: Maybe *your* Haskell compiler can't.
gollark: And this can be statically verified.
