Stainless Steel 317L Couplings manufacturer

317L Stainless Steel couplings are a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

SUS 317L Couplings 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 Couplings Heat Treatment

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

SS 317L Couplings Fabrication

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

317L Stainless Steel Couplings 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 Couplings Machining

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

317L Couplings Welding

Alloy 317L Couplings 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 Couplings Hot Forming

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