Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, A573 grade 70 steel sheet.
GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. A573 grade 70 steel sheet, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.
