S500Q high strength steel plate

S500Q high strength steel plate also named as S500Q high strength low alloy steel plate under steel stand EN 10025-6 which is for hot rolled structural steels with high yield strength and tensile strength in quenched and tempered delivery condition.Quenching operation which consists of cooling a ferrous steel plate more rapidly than in still air.Tempering heat treatment applied to a ferrous steel plate generally after quench hardening or other heat treatment to bring the properties to the required level. High yield strength steel plate S500Q under EN 10025-6 owned the minimum yield strength at 500 Mpa and tensile strength within 590-770 Mpa.
