Which grades do you supply to ASTM B575?
Hastelloy C276, Hastelloy C22 — see the table on this page for the exact product and designation.
What is the difference between ASTM B575 and ASME SB-575?
ASME SB-575 is the ASME Boiler and Pressure Vessel Code (Section II) adoption of ASTM B575. The technical requirements are usually identical to a specific ASTM edition; pressure-equipment codes call for the ASME designation, and most mill certificates show both.
Do you supply certificates to this standard?
Yes. Material is supplied with mill test certificates to EN 10204 3.1 showing the standard, grade and heat number; 3.2 with third-party inspection on request.
