Weathering steel plate is a steel plate that is resistant to atmospheric corrosion, which is a series of low alloy steels between ordinary steel and stainless steel. Weathering steel plate is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel added. According to its main characteristics, it is divided into high weather resistance structural steel plate and weathering steel plate for welded structure. Weathering steel realizes sustainable development and innovation after integrating into new modern metallurgical mechanisms and new technologies, and is one of the series of steels at the forefront of world technology. 

High weathering steel plate

High weather resistance structural steel is to add a small amount of copper, phosphorus, chromium and nickel elements to the steel to form a protective layer on the surface of the metal collective to improve the atmospheric corrosion resistance of the steel, and a small amount of molybdenum, niobium, Vanadium, titanium, zirconium and other elements are used to refine the grains, improve the mechanical properties of the steel, improve the strength and toughness of the steel, reduce the brittle transition temperature, and make it have better resistance to brittle fracture.

The use of high weather resistance structural steel is mainly used for bolted, riveted and welded structural parts for vehicles, containers, buildings, towers and other structures due to its better atmospheric corrosion resistance than weathering steel for welded structures.

 Low-carbon steel plate

Low-carbon steel plate is a kind of material with a large amount of use, which is divided into ordinary low-carbon steel plate and special steel plate, including low-alloy high-strength steel and corrosion-resistant and heat-resistant clad steel plate. Ordinary low-carbon steel sheets are divided into two types: cold-rolled and hot-rolled. Cold-rolled steel sheets have good surface quality and precise thickness and dimensions, and are mostly used in the manufacture of car bodies. Hot-rolled sheets are mostly used in the manufacture of frames and the like.
