317L Stainless Steel Tubing

Similar in composition to 316L and 304L, alloy 317L is an austenitic molybdenum, chromium, nickel stainless alloy. Due to the higher moly content, 317L provides enhanced resistance to pitting and stress corrosion cracking particularly in chloride or halide-rich environments. 317L has higher creep, stress-to-rupture, and tensile strength than its 316L and 304L counterparts which makes it a great solution to demanding applications found offshore, in pulp & paper mills and in chemical processing plants.

Fabrication

The low carbon content provides resistance to intergranular corrosion and superior weldability over 316. 317L can be hardened by cold working as opposed to heat treating.
