Since it was established in 2000. Based on the domestic rich A572 grade 55 high strength steel product resources and the great steel demand of the international market, our A572 grade 55 high strength steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
Scope of application of JIS G3101A572 grade 55 high strength steel : SS400 steel plates and other steel products are suitable for general structural buildings, bridges and ships, and the final products are hot rolled products.
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the A572 grade 55 high strength steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
In order to improve the A572 grade 55 high strength steel corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main A572 grade 55 high strength steel coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking A572 grade 55 high strength steel sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world
