S620Q High yield strength steel plate
Source:Xin Steel Industry Date:2013/05/03
S620Q high strength steel plate also named as S620Q 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 S620Q under EN 10025-6 owned the minimum yield strength at 620 Mpa and tensile strength within 700-890 Mpa.
