317L Stainless Steel
Introduction
Overview of 317L Stainless Steel
317L stainless steel is a low carbon version of the more common grade 316L stainless steel. The “L” in the name indicates that it is a low carbon version, and the number represents the chromium content in percent.
317L stainless steel is slightly less resistant to corrosion than 316L, but has better formability and weldability.
In addition, compared with conventional stainless steel, 317L stainless steel has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance.
Futures of 317L Stainless Steel
Stainless steel 317L has a higher creep strength than 304 stainless steel and can be used at temperatures up to 538°F (280°C).
317L stainless steel can be welded similarly to 304 with the use of preheating when welding dissimilar materials.
The high chromium content of this grade gives it good resistance to chloride ion stress corrosion cracking in the presence of chlorides at elevated temperatures. The low carbon content means that it does not have as much carbon monoxide cracking resistance as other grades such as 304L stainless steel or 316L but is still better than standard 304 stainless steel.
