What is chemical composition of S355J2G1W hot rolled corten steel section

Q355GNH weather-resistant steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel. S355J2G1W hot rolled corten steel section, Q355GNH alloy steel plate and sheet are mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

Heat treatment is a very important process to improve the performance of S355J2G1W hot rolled corten steel section etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

There are many kinds of heat treatment processes for wear-resistant composite plate, S355J2G1W hot rolled corten steel section, and they are applicable to different ranges. For example, direct quenching and low-temperature tempering can not refine the grain size of steel, the quenching deformation of workpiece is large, and the surface residual austenite volume of carburized parts of hardfacing wear-resistant composite plate is more, and the surface hardness is lower. It is suitable for gas carburizing and liquid carburizing.

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.
