ATI Allegheny Ludlum Martensitic Stainless Steel Type 420HC
Categories:	Metal; Ferrous Metal; Stainless Steel; T 400 Series Stainless Steel
Material Notes:	Allegheny Ludlum Type 420HC is a hardenable straight-chromium stainless steel which combines superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels. Oil quenching this alloy from temperatures between 1800°F and 1950°F produces the high strength and/or wear resistance as well as corrosion resistance. A major use for this grade of heat treatable stainless steels is in cutlery. When blanking cutlery parts from annealed raw material stock, Type 420HC will usually exhibit hardness, yield strength, and tensile strength that are low enough for fine blanking purposes. Type 420HC is a high carbon version of Type 420. When sufficient amounts of carbon are added to straight-chromium stainless steel, the alloy then has the capability to transform its microstructure through proper heat treatment (hardening) into one that will possess optimum strength , hardness, edge retention, and wear resistance.
