Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms,PVQ A387 grade 22 class 2 boiler steel plate.

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.

Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows Chemical composition (C: 008 to 020; Cr: ≤030; Si: ≤040; Cu: ≤030;Mn: 090 to 150; Mo: ≤008;P: ≤0025; Nb: ≤0020;S: ≤0015; Ni: ≤030;Al: ≤0020; Ti: 003; N: ≤0012; Vi: ≤002) The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa,PVQ A387 grade 22 class 2 boiler steel plate.
