Which grades are covered by ASTM A268?
On this site: SS 409, SS 410, SS 430, SS 446.
Do you supply material certified to ASTM A268?
Yes. Material is supplied to ASTM A268 with EN 10204 3.1 certificates (3.2 on request), where the mill certifies to it.
Is ASME SAA268 the same as ASTM A268?
ASME adopts many ASTM material specifications into Section II with an "S" prefix (for example SA-268). The adopted text is identical or includes stated modifications, and dual-certified material meets both.
