Sale S690QL australian equivalent for steel pipe

The smelting of S690QL australian equivalent, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to have high purity. The content of sulfur, phosphorus, oxygen and nitrogen should be low, and the uniformity and stability of steel should be good. The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, spring steel must also have some characteristics.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the S690QL australian equivalent steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of S690QL australian equivalent extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
