At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A564. Hot-rolled and cold-finished age-hardening (precipitation-hardening) stainless steel bars, wire and shapes for parts requiring corrosion resistance and high strength at room temperature or up to ~600 deg F (315 deg C). Machinable in the solution-annealed condition then aged to the required condition (H900, H1025, H1075, H1150, etc.). Common fastener grades: Type 630 (17-4PH), Type 631 (17-7PH), XM-12 (15-5PH), XM-13 (13-8Mo).

ASME SA-564 (BPVC Sec. II) is the ASME adoption of ASTM A564/A564M with essentially identical content. Type 630 = 17-4PH = UNS S17400 = 1.4542 = AMS 5643; Type 631 = 17-7PH = UNS S17700. Properties vary with product thickness/orientation – see standard Table 3.
