Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with SMA490BW steel strip, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.
The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the SMA490BW steel strip, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.
The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the SMA490BW steel strip steel materials can be shipped immediately after passing the quality inspection.
Specification range of available steel SMA490BW steel strip: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates SMA490BW steel strip can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
