Savoy Piping Inc. supplies 309S — a heat-resisting austenitic grade for oxidation and high-temperature atmospheres above common 304/316 service.
Grade hub · A312 Seamless · A312 Welded · A213 · A269 · A358 EFW · SS hub
Also see: Stainless steel pipe & tube hub · Buttweld fittings · Flanges · Materials hub.
309S (UNS S30908): high Cr-Ni (~23Cr-13Ni) low carbon. Mechanical guide: per SA-312 TP309S — confirm PO.
Use 309S for oxidation resistance. For still hotter / more severe service consider 310S.
309S vs 310S: 310S has higher Cr-Ni for more severe heat.
