AISI 310S · UNS S31008
An SS 310 / 310S welded pipe is pipe formed from plate or strip and welded along its length, made from SS 310 / 310S to ASTM A312 · A358. Welded (ERW / EFW) pipe is economical in larger diameters and thinner walls, and accepted by most codes with the right testing.

SS 310 / 310S Welded Pipe: Why 310S for welded pipes
Welded (ERW / EFW) pipe is economical in larger diameters and thinner walls, and accepted by most codes with the right testing. In SS 310 / 310S, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Stainless tubulars are the default for corrosive and hygienic service. SS 310 / 310S is picked for furnaces, burners and heat treatment at high temperature. |
|---|---|
| Typical service | Furnace parts — Muffles, retorts, radiant tubes and conveyor belts. |
| Welding to carbon steel | ER309L (or E309L electrode) is the usual filler when joining it to carbon steel |
| Matching filler | ER310 (AWS A5.9) |
