Steel for Boilers and Pressure Vessels

P235 GH, P 265 GH, P 295 GH steel plate P 275 N, P 275 NHP, 275 NL 1 steel plate SB 410 ,SB 450, SB 480 steel plate
Pressure vessel and boiler quality steel are commonly used throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry.
Boiler steel plate has good strength, it can be made of boilers and components to withstand a certain long-term high temperature stress; Boiler steel plate has good toughness and low effectiveness of the tendency in the use of bending, curling, deformation processing such as cold, after more prolonged storage and use remains a good toughness; Boiler steel plate also has good weldability and resistance to intergranular corrosion. For the manufacture of boiler drum, beams and wall panels.
Steel for Pressure Vessels contains:Low-temperature low-alloy steel for pressure vessel, normal temperature pressure uses the steel,Quenched and tempered high strength steel plates for pressure vessels.
The delivery condition of Boilers Steel are: Normalize, annealing,tempering,TMCP,PWHT, impact test,Q&T.

Main steel grades of Pressure vessel and boiler quality steel:
