Stainless Steel 317L Union manufacturer

317L Stainless Steel Union, similar to a coupling, allows the convenient future disconnection of pipes for maintenance or fixture replacement. In contrast to a coupling requiring solvent welding, soldering, or rotation (for threaded couplings), an AISI 317L Union allows easy connection and disconnection, multiple times if needed.

SS 317L Union consists of three parts: a nut, a female end and a male end. When the female and male ends are joined, the nut seals the joint by pressing the two ends tightly together. Grade 317L Stainless Steel Unions are a type of very compact flange connector.

SUS 317L Union Heat Resistance

Significantly better corrosion resistance that T-316 in the same environments. Good oxidation resistance in continuous service to 925°C and in intermittent service to 879°C.

AISI 317L Union Heat Treatment

AISI 317L Union is non-magnetic in the annealed condition and is non-hardenable by heat treatment. Machinability is 39% – 65 surface feet per minute.

SS 317L Union Fabrication

Alloy 317L Union can be easily welded and processed by standard shop fabrication practices.

317L Stainless Steel Union producing through Cold forming

Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended.

Stainless Steel 317L Union Machining

Low speeds and constant feeds will minimize this alloy’s tendency to work harden. Tougher than 304 stainless Union with a long stringy chip, the use of chip breakers is recommended.

317L Union Welding

Alloy 317L Union can be readily welded by most standard processes. A post weld heat treatment is not necessary. 317L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of 317L, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of 317L should be used to weld 317L steel.

Alloy 317L Union Hot Forming

AISI 317L Union is non-magnetic in the annealed condition and is non-hardenable by heat treatment. Machinability is 39% – 65 surface feet per minute.
