Table Of content

Stainless steel 317 flanges are made of austenitic stainless steel that includes chromium and nickel. It has excellent corrosion resistance. Stainless steel 317 flanges are more durable than stainless steel 304 flanges. Stainless steel 317 flanges have a high content of molybdenum which improves its pitting resistance properties. They can be welded using the fusion and resistance methods. It is recommended to not use the Oxyacetylene welding method for stainless steel 317 flanges. They offer great properties such as high tensile strength, high yield strength, and excellent creep-rupture properties. Stainless steel 317 steel can be hot worked by using the most common hot working procedures. Stainless steel 317 flanges are used across a wide range of industries for different applications, like condensers in fossil industries, Pulp, and paper manufacturing industries, Nuclear fueled power generation stations, and Chemical and petrochemical process industries.

Stainless steel 317 flange, which is a low-carbon variation of the stainless steel 317 flange is the stainless steel 317L flange and has the same high strength and corrosion resistance as stainless steel 317 flanges, but because of the low carbon content, it is easier to weld. They have good weldability due to the lower carbon content. It is recommended that Oxyacetylene welding should be avoided. Standard hot working processes can be performed. Stainless steel 317L should be heated to 1149-1260°C (2100-2300°F); however, it should not be heated below 927°C (1700°F). Post-work annealing is recommended to increase corrosion resistance. It is also non-magnetic in its annealed condition. Stainless steel 317L grade will not respond to heat treatment but will harden due to cold working. It displays good strength and toughness at cryogenic temperatures. Stainless steel 317L flanges are available in many varieties like weld neck flange, screw neck flange, etc.
