ASTM A606 Type 4 Weathering Steel Sheet is a standard steel specification for high-strength, low-alloy, hot- and cold-rolled steel sheet and strip with improved resistance to atmospheric corrosion for structural and other applications. There are two types, type 2 and type 4. Compared with ordinary structural Carbon Steel Plate, ASTM A606 type 4 has 4 times higher atmospheric corrosion resistance. It has good weldability, formability and machinability with proper treatment. Weathering structural steel is atmospheric corrosion-resistant steel, which belongs to low-alloy high-strength structural steel. High weathering 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. A small amount of molybdenum, niobium, vanadium, titanium, zirconium and other elements are used It is used to refine grains, improve the mechanical properties of steel, increase the strength and toughness of steel, reduce the brittle transition temperature, and make it have better resistance to brittle fracture.

The steel plate is a flat steel that is cast with molten steel and pressed after cooling. The steel sheet is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling.
1. Hot Rolled Steel Plate
Hot rolling processing methods include hot rolling, forging, extrusion and other methods.
2. Cold Rolled Steel Plate
Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods.
The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.
