Alloy Resistant Steel NM500

NM500 steel plate refers to quenched and tempered steel plate, which is a type of high-strength steel that has been heat-treated to improve its mechanical properties. The quenching process involves rapidly cooling the steel plate in water or oil to harden it, while the tempering process involves reheating the steel plate to a specific temperature and then allowing it to cool slowly to improve its toughness and ductility.

This grade material provides maximum wear resistance from impact and sliding. The fine grained, thru-hardened alloy steel chemistry makes this plate have the optimum hardness/toughness ratio. NM500 is available in thicknesses from 1/8'' to 4'' and can be cut by gas, abrasive water jet, laser, or plasma.
