High Quality Hot Rolled A537 GL.2 Pressure Vessel Steel Plate Factory Price
1.Introduction of A537 GL.2 pressure vessel steel plate
A537 GL.2 pressure vessel steel plate is mainly refers to used to make superheater tube boiler, the main steam heating room with fire and hot rolling steel plate material, the main material is high quality structural steel and low alloy steel heat, the commonly used boiler steel smelting steel mill have the low carbon steel smelting furnace of calm or low carbon steel, carbon content in Wc, 0.16%-0.26% range. Due to the boiler plate in temperature (350 and ordm; C below) work under high pressure, in addition to withstand higher pressure outside, still affected, fatigue load and water and corrosion of steel of boiler performance requirements of the main is to have good welding and the cold bending property, certain high temperature strength and alkali resistance, resistance to oxidation and corrosion.
Boiler and pressure vessel with board basically steel grade and standards
(1) boiler plate mainly has: 20 g, 16 Mng, 15 CrMoVg, 19 Mng, 22 Mng
(2) pressure vessel with steel grade board basically have: 20 R, 16 MnR, 15 MnNbR, 15 MnVNR P235GH P265GH P295GH P355GH
3) standards: GB713-1997, GB6654-1996
