INTRODUCTION
Stainless steel grade 317L is a low carbon version of grade 317 stainless steel. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.
Stainless Steel 317L Pipes that are made using high-tech machinery and top notch technology. We always procure our products from certified vendors. These pipes are known for long lives, robust construction, and corrosion resistance and are widely used in construction, oil & gas, petrochemical, natural gas as well as other industries. These are tested on supreme quality parameters and are offered in seamless, erw, welded and fabricated forms.
Stainless Steel 317 L Sheets in the grades of 317 L. They are developed with the help of exquisite technology and are offered in various dimensional specifications. These SS plates and sheets are tested on different quality parameters and are used in numerous fabrication and engineering projects. These plates and sheets are carefully designed and customized in complete accordance with customer’s varied specifications.

Manufacturing Process
Machining stainless steel grade 317L requires low speeds and constant feeds to reduce its tendency to work harden. This steel is tougher than grade 304 stainless steel with a long stringy chip; however, using chip breakers is recommended. Welding can be performed using most of the conventional fusion and resistance methods. Oxyacetylene welding should be avoided. AWS E/ER 317L filler metal is recommended.
Conventional hot working processes can be performed. The material should be heated to 1149-1260°C (2100-2300°F); however, it should not be heated below 927°C (1700°F). To optimize corrosion resistance, a post-work annealing is recommended.
Shearing, stamping, heading and drawing are possible with grade 317L stainless steel, and post-work annealing is recommended to eliminate internal stresses. Annealing is performed at 1010-1121°C (1850-2050°F), which should be followed by rapid cooling.
Grade 317L stainless steel does not respond to heat treatment
