On this site: SS 304, SS 304L, SS 316, SS 316L, SS 321, SS 347, SS 410, Duplex 2205, Super Duplex 2507.
Do you supply material certified to ASTM A479?
Yes. Material is supplied to ASTM A479 with EN 10204 3.1 certificates (3.2 on request), where the mill certifies to it.
Is ASME SAA479 the same as ASTM A479?
ASME adopts many ASTM material specifications into Section II with an "S" prefix (for example SA-479). The adopted text is identical or includes stated modifications, and dual-certified material meets both.
