Web440C (UNS designation S44004) is a martensitic 400 series stainless steel, and has the highest carbon content of the 400 stainless steel series. It can be heat treated to reach hardness of 58 to 60 HRC.It can be used to make rolling contact stainless bearings, e.g. ball bearings and roller bearings.It is also used to make knife blades.. 440C has the … Web55 HRC is a very high hardness, even for steels. Ideally the corrosion resistance of the steel would have to match AISI 316L or be even better. Qenched stainless steel can go to 55HRC. Even to 65 HRC. But this is at the price of a high Carbone content. Carbone react with free Chromium and makes it unavailable for corrosion resistance.
