A455 STEEL PLATE

A455,A455 steel plate,A455 steel sheet high strength carbon-manganese steel material is mainly used for welded boiler and pressure vessel buildings.When rolling A455 steel plate,it usually made to a semi-killed or capped deoxidation,normally supplied in the as-rolled delivery condition.and also may be ordered under normalized or stress relieved or both.Besides the basic technical requirements for boiler steel plate SA455,the supplementary requirements such as simulated post welded heat treatment and bend test.
 

Technical Requirements & Additional Services:
♦ High tension test
♦ Low temperature impacting test
♦ Simulated post-welded heat treatment (PWHT)
♦ Rolling under standard NACE MR-0175 (HIC+SSCC)
♦ Issued Orginal Mill test certificate under EN 10204 FORMAT 3.1/3.2
♦ Shot blasting and Painting,Cutting and welding as per end user’s demands
