P355QL2 steel grade is quenched and tempered steel grade for weldable fine grain pressure purposes.P355QL2 Grade has a good weldable and used in high temperature equipment and pressure vessel.
Boiler steel plate P355QL2 and Pressure vessel steel plate P355QL2 need to be done heat treatment under Quenched and tempered when delivery.For improving steel property of plate P355QL2,Simulate post weld heat_treatment conditions can decrease the mechanical properties,so our engineers suggest the end users choose this technical terms when they making orders.We would issue the PWHT report and indicate the values of test pieces.Now Katalor roll boiler steel sheet p355ql2,the maximum thickness can reach till 350mm,and the maximum unit weight can reach till 28 tons.
Additional Condition :
UT (Ultrasonic examination), AR (As Hot Rolled only), TMCP (Thermal Mechanical Control Processing), N(Normalized), Q+T (Quenched and Tempered), Z Direction Test (Z15, Z25, Z35) ,Charpy V-Notch Impact Test, HIC test, NDT, PWHT( Simulated Post Weld Heat Treatment), NACE0175, The Third Party Test (Such as SGS Test), Coated or Shot Blasting and Painting.
