S890Q,S890Q steel plate,S890Q steel sheet also named as S890Q high strength low alloy steel plate under steel specification 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.
