On this site: SS 304L, SS 316L, SS 321, SS 347, SS 317L.
Do you supply material certified to ASTM A262?
Yes. Material is supplied to ASTM A262 with EN 10204 3.1 certificates (3.2 on request), where the mill certifies to it.
Is ASME SAA262 the same as ASTM A262?
ASME adopts many ASTM material specifications into Section II with an "S" prefix (for example SA-262). The adopted text is identical or includes stated modifications, and dual-certified material meets both.
