S460Q STEEL PLATE

High strength S460Q steel plate also named as S460Q high strength low alloy steel plate under steel standard EN 10025-6 specification 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.S460Q shall be done low temperature impacting test under minus 20 centigrade.
