Stainless steel 317L tubing is new but low carbon version of stainless steel 317 grade. It is having the excellent feature of high strength and resistance to corrosion as this grade tube can because of the low content of carbon can produce the stronger weld. To machine, the stainless steel 317L tubes need constant feed and low speed for reducing work harden tendency. The steel is tougher and using chip breaker is suggested. Welding can be done by using resistance and conventional fusion technique. However Oxyacetylene welding technique is to be avoided. The AWS ER/E filler metal is suggested.
The conventional hot working method can be done. The material must be heated at 2100?F to 2300?F. It must not be heated below 1700?F. For optimizing resistance to corrosion feature, post work annealing method is recommended. Stamping, shearing, drawing, and heading are possible easily with Stainless steel 317L tubing. Post work annealing is suggested for purpose of eliminating the internal stres
