SMA400BP atmospheric corrosion resisting steel sheet controlled rolling is that, on the basis of adjusting the chemical composition of SMA400BP atmospheric corrosion resisting steel sheet, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of SMA400BP atmospheric corrosion resisting steel sheet.

The preparation of SMA400BP atmospheric corrosion resisting steel sheet galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for SMA400BP atmospheric corrosion resisting steel sheet centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
