Also see: Stainless steel pipe & tube hub · Buttweld fittings · Flanges · Materials hub.
310S (UNS S31008): high Cr-Ni (~25Cr-20Ni) low carbon. Mechanical guide: per SA-312 TP310S — confirm PO.
Specify 310S when temperature/oxidation exceeds 309S capability. Not a chloride pitting upgrade over 316 — different job.
310S vs 309S: more Cr/Ni for hotter service. 310S vs 321: 321 is stabilised process grade, not a furnace substitute.
