Which grades are covered by ASTM B574?
On this site: Hastelloy C276, Hastelloy C22.
Do you supply material certified to ASTM B574?
Yes. Material is supplied to ASTM B574 with EN 10204 3.1 certificates (3.2 on request), where the mill certifies to it.
Is ASME SAB574 the same as ASTM B574?
ASME adopts many ASTM material specifications into Section II with an "S" prefix (for example SA-574). The adopted text is identical or includes stated modifications, and dual-certified material meets both.
