Product Details
317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher. Stainless 317 L has a high tensile and creep strength at elevated temperatures. Due to its excellent corrosion resistance it has been used in handling many of the chemicals used by the chemical process industries. t has a superior corrosion resistance in special applications where it is desired to reduce contamination to a minimum.
317L was developed primarily to resist more effectively the attack of sulfurous acid compounds. However, its proven ability to combat corrosion has widened its use considerably and is now being used for many other industrial applications. The low carbon content of 317L provides immunity to intergranular corrosion in applications where heavy cross sections cannot be annealed after welding or where low temperature stress relieving treatments are desired.
317L (00Cr19Ni13Mo3, SUS317L) alloy is based on molybdenum and austenitic stainless steel. It is more resistant to chemical corrosion than normal chrome-nickel austenitic stainless steel, such as 304 alloys. In addition, compared with conventional stainless steel, 317L alloys have higher ductility, anti-stress corrosion, compressive strength and high temperature resistance. It is a low carbon grade or L rating, which has the ability to resist sensitization during welding and heat treatment.
