Do I need to make a requalification for corten steels acc. ASME section IX if I have PQR` from P1. In fact What are the ASTM equivalents (P no and group No.) of Corten A and Corten B steels? Huseyin Sari China
Thanks for the info.One more question is, We are using ASME standarts for PQR`s ,WPS`s etc. To make a new qualification with Corten A and Corten B, which P no. shall be selected for testing acc .to ASME section IX.
The ASTM standard for CorTen plate is A-588. This does not have a P-number, but is assigned S-number 3 in ASME IX. A procedure qualification on P-number 3 also qualifies for S-number 3. You will have to also look at the A-number of the PQR to be used to make sure it covers the electrode. Corten is usually welded with E7018 or E8018-W2 for color matching. I have also seen it welded with E8018-C3.
