Alloy 20 Forged Fittings

Q: Socket weld or threaded — which end type?

Socket weld for permanent high-integrity joints; threaded where welding is restricted or disassembly is needed.

Alloy 20 Socket Weld Fittings — ASTM B462 / B564 UNS N08020

Savoy Piping Inc. manufactures and supplies alloy 20 socket weld fittings in socket weld and threaded ends for small-bore process and utility piping. Dimensions follow ASME B16.11 (and MSS SP-79 / SP-83 / SP-95 where applicable).

What is this material?

Alloy 20 (UNS N08020) forged fittings are used for sulfuric acid and related chemical service where standard stainless is marginal. Supplied socket weld and threaded to ASME B16.11.

Selection guidance

Specify Alloy 20 / UNS N08020, end type, NPS and class. Related options include SMO 254 and Hastelloy when the chemical duty differs.

What to put on the PO

Include material grade / ASTM class, end type (socket weld or threaded), fitting form, size, pressure class, quantity, destination, and documentation (EN 10204 3.1 / 3.2, PMI, NACE, TPI). Email sales@savoypipinginc.com.
