What is 317L Stainless Steel Seamless Tube?

Stainless Steel 317L Seamless Tube is manufactured using a process called “extrusion”. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube. Basically there are two types of 317L seamless tube: ASTM A213 TP317L Cold Drawn Seamless (CDS) and ASTM A213 TP317L Hot Finished Seamless (HFS) Tube.

SUS 317L Seamless Tube 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 Seamless Tube Heat Treatment

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

317L Seamless Tube Welding

Alloy 317L 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.

SUS 317L Seamless Tube Corrosion Resistance

317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion.

Stainless Steel 317L Seamless Tube Machinability

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

317L Seamless Tube producing through Cold forming

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

SS 317L Seamless Tube Fabrication

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

317L Stainless Steel Seamless Tube Applications & Usage:

Some of the major applications of grade stainless steel 317L Seamless Tube include:
