Weathering steel plate grades

Weathering steel, that is, atmospheric corrosion-resistant steel, is a low-alloy steel series between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. Extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance and other characteristics;

The weather resistance is 2~8 times that of ordinary carbon steel, and the paintability is 1.5~10 times that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, labor saving and energy saving.

Weathering steel is mainly used for steel structures that are exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects. It is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipment.

Weathering steel grades: 05CuPCrNi-A, 09CuPCrNi-A, SPA-H, B480GNQR, Q400NQR1, Q450NQR1, Q550NQR1, Q700NQR1, Q235NH, Q295NH, Q355NH, Q460NH, Q295GNHL, Q345GNHL, Q460GNHL, Corten-A, COR-TEN, B450NHL B460NQ, Q500NQ, NMIE0921, NM360, NM400, Q450NQR1, etc.
