S460Q high strength low alloy steel
S460Q high tensile steel sheet is a tempered high strength steel sheet, 'S' stands for its trademark for the European standard specification.
S460Q high tensile alloy steel has good strength and impact toughness, and can be used in the manufacture of some of the requirements for the strength and toughness of the steel sheet parts.
S460Q high strength structural steel is mainly used in the manufacture of low-temperature resistant, high-strength key components, construction machinery, mining machinery structure, etc., is a high-strength structural steel plate.
