410, 420, 440A, 440C stainless steel ( martensitic ) sheets, plates

(UNS S41000/S42000/S44002/S44004)


AISI 410, 420, 440A and 440C alloys  are hardenable, straight-chromium stainless steels which combine superior wear

resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels.

Oil quenching these alloys from temperatures between 1800°F to 1950°F (982-1066°C) produces the highest strength and/or

wear resistance as well as corrosion resistance. A range of as-quenched hardness is achieved in these alloys by varying the

carbon level from 0.15% maximum in Type 410 alloy to 0.60-0.75% in 440A alloy.
These alloys are used where strength, hardness, and/or wear resistance must be combined with corrosion resistance.

A major use for these grades of heat treatable stainless steels is in cutlery. Depending on the customer's end-use requirements, cutlery alloys are usually selected with respect to heat treating response, mechanical properties and fabricating characteristics.
