EN10155 S235J2W is a kind of low alloy steel between carbon steel and stainless steel.
EN10155 S235J2W is made of carbon steel with a small amount of corrosion resistant elements such as copper and nickel. It has the characteristics of toughness, ductility, forming, welding, abrasion, high temperature and fatigue resistance of high quality steel.
EN10155 S235J2W is mainly used in railway, vehicles, bridges, towers, photovoltaic, high-speed engineering and other long-term exposure to the atmosphere of steel structures. It is used to manufacture structural parts such as containers, railway vehicles, oil derricks, harbour buildings, oil platforms and containers containing hydrogen sulfide corrosion media in chemical and petroleum equipment.

EN10155 S235J2W steel has good atmospheric corrosion resistance. Although the investment cost of applying EN10155 S235J2W steel is slightly higher than that of carbon steel, compared with the methods of spraying anticorrosive coating on the surface of carbon steel, the maintenance cost of carbon steel is 1.5-2 times of EN10155 S235J2W steel. Therefore, EN10155 S235J2W steel can reduce environmental pollution, which belongs to the key popularization technology of energy saving and emission reduction.
