high strength, moderate corrosion resistance, and good hardness and
wear resistance. 440 441 444 446 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 the materials particularly suited to such
applications as ball bearings and valve parts.
