What is SS 316 / 316L buttweld fittings?

Dual certification covers both 316 and 316L limits on the same heat when issued — verify on the MTC.

Typical applications

  • Oil & gas and refining piping
  • Chemical and petrochemical process lines
  • Power, water, and industrial utility systems

Selection guidance

Specify dual only if the project allows; otherwise order 316L or 316 explicitly.

Frequently asked questions

What are SS 316 / 316L buttweld fittings?

SS 316 / 316L buttweld fittings are ASME B16.9 (and related) butt-weld pipe fittings used to change direction, branch, reduce, or close a line with a full-penetration weld.

Which standards apply?

Dimensional: ASME B16.9 / B16.28. Material: ASTM/ASME grade specs (e.g. A403, A234, A420, A860, A815, B366). Confirm edition and WP/WPHY class on the PO.

Seamless or welded fittings?

Both are supplied. Seamless is common for smaller sizes; welded (fabricated) covers larger OD. Match the construction to your piping class.

What should be on the purchase order?

Grade/UNS, fitting type and degree/radius, size/schedule or wall, seamless or welded, standard (B16.9), quantity, MTC (EN 10204 3.1/3.2), and any NACE/PMI/NDT extras.

What is the ASTM twin for SS 316 / 316L?

Material for wrought austenitic fittings is typically ordered to ASTM A403 WP316/316L. See the linked A403 twin page.
