The overall chemical composition of EN10210 S355J2H hot-rolled pipe is 0.22% carbon, 0.55% silicon, 1.6% manganese, 0.03% phosphorus and sulfur. The addition of more manganese gives it good toughness and ductility compared with low carbon steel pipes. Due to carburizing, the surface toughness of EN10210 S355J2H carbon steel pipe can be greatly improved.
In terms of physical properties, the yield strength of EN10210 S355J2H hot-rolled structural pipe reaches 355MPa, and the tensile strength is as high as 470-630MPa, which makes it highly reliable under heavy loads and high pressures. At the same time, its impact energy can reach more than 27J at -20°C, which belongs to low-alloy high-strength steel.
