AISI 316L · UNS S31603
An SS 316 / 316L bend is a pipe bend with a larger radius than a standard elbow, made from SS 316 / 316L to ASTM A403 WP316L. Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe.

SS 316 / 316L Bend: Why 316L for bends
Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe. In SS 316 / 316L, 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 fittings keep the line clean and corrosion-free. SS 316 / 316L is picked for chloride-bearing process fluids, marine air and pharmaceutical service. |
|---|---|
| Typical service | Chemical & process — Piping and vessels handling mild acids and chlorides. |
| Welding to carbon steel | ER309L (or E309L electrode) is the usual filler when joining it to carbon steel |
| Matching filler | ER316L (AWS A5.9) |

Bend or elbow — what is the difference?
An elbow has a fixed 1D or 1.5D radius to ASME B16.9; a bend is bent from pipe to a larger radius, typically 3D or 5D.
Can SS 316 / 316L bends be welded to carbon steel?
Yes — ER309L (or E309L electrode) is the usual filler when joining it to carbon steel.
Which standard covers SS 316 / 316L bends?
The material is ASTM A403 WP316L; dimensions follow ASME B16.49 · project specs. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a SS 316 / 316L bend?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
