The fake and inferior A588 Gr B high strength steel, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
The development A588 Gr B high strength steel of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with A588 Gr B high strength steel high-quality and efficient services, work together for win-win, and create a better tomorrow!
Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, A588 Gr B high strength steel product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.
According to different purposes, the thin steel sheets are rolled from billets of different materials. Commonly used materials include plain carbon steel, such as A588 Gr B high strength steel, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, and silicon steel for electrical purposes. The thin steel sheets are mainly used in the automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to delivery directly after rolling, there are also pickled, galvanized and tinned thin steel sheets.
