S355JR is a low alloy high strength structural steel according to European standard EN10025.S355JR is low alloy high strength structural steel in China steel, the hardness is 70-80B, the yield strength is between 300-400MPa.
S355JR is classified as low alloy high strength structural steel, is the European standard steel plate, S355JR steel plate performance characteristics, than ordinary carbon structural steel has a higher yield strength and yield strength ratio, better hot and cold machining and forming, good weldability, lower tendency to cold embrittlement, notch and aging sensitivity, as well as better resistance to corrosion of the atmosphere, seawater and other corrosion capabilities.
S355J2 steel plate delivery status: S355JR delivery hot rolled, controlled rolled, normalised and so on.
S355J2 steel plate is commonly used in ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transport machinery and other higher loads of welded structural components, large ships, bridges and sorghums, power station equipment, medium- and high-pressure boilers, high-pressure containers, rolling stock, lifting machinery, mining machinery and other large-scale welded structural components, for a variety of large-scale engineering structures and lightweight structures that require high strength and large loads The products are used in various large engineering structures and light structures requiring high strength and large load.
