what is Q355GNH steel for general intermediate strength applications

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the what is Q355GNH steel industry, keep pace with the times, and move towards a new course!

The company has strict control on the quality of what is Q355GNH steel. Each what is Q355GNH steel is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the what is Q355GNH steel meets the specified quality requirements. If the what is Q355GNH steel does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified what is Q355GNH steel shall be removed, marked, registered and effectively isolated; the what is Q355GNH steel shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, what is Q355GNH steel, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

The chromium plays an important role in what is Q355GNH steel, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The what is Q355GNH steel, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
