?Chemical composition for A516 Grade 70 boiler steel (Product Analysis Max%)
Sa516 Grade 70 are mainly used in welded pressure vessels where improved notch toughness is important.Generally As rolled is ok for rolling pressure vessel steel plate A516Gr70,however,for improve steel property and toughness,we suggest the end users accept rolling A516 Grade 70 steel plates under Normalized,especially for the steel plates thickness above 40mm.NACE MR-0175 A516 Grade 70 also offered by us with HIC test and SSCC test.
Technical Requirements & Additional Services:
♦ High tension test
♦ Low temperature impacting test
♦ Normalised for thick plates over 40mm
♦ 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
