EN 10210/S355 Seamless Steel Pipe -

Product Description EN 10210/S355 Seamless Steel Pipe

S355 steel pipe has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low cold brittle critical transition temperature. The use of high-strength low-alloy steel can effectively reduce the weight of the structure, improve the strength and stiffness of the structure, and improve durability while reducing the thickness of the structure. S355 seamless steel pipes are commonly used in the production of bridges, ships, power station equipment, lifting and transportation machinery, machinery manufacturing and other engineering and welded structural parts that bear higher loads.
