Accreditation Administration System:
According to the various yield strength,the steel gardes are listed as P235GH,P265GH,P295GH and P355GH.
They belong to non alloy steel plates with specified elevated temperature properity which mainly intended for
building boilers and pressure vessels.
The heat treatment shall be Normalized for each thickness.Our rolling thickness range these gardes shall be
within 8-350mm.
P265GH is a weldable pressure vessel and boiler steel grade used by the world's industrial fabricators. Generally,
these supplementary demands from customer would be issued in order:
S3.Simulated Post:Weld Heat Treatment,customer shall indicate us in their order about times of heat cycles,the
temperature of treatment and the time of heat preservation.
S5.Impactting Test.
S8.Ultrasonic Examination shall be done according with EN10160_1999,including such standards S2E2,S1E2
and S0E2.
The technical specifications of P265GH are outlined in the tables below:
