Alloy 317L (UNS S31703) is a molybdenum - bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium - nickel austenitic stainless steels such as Alloy 304. In addition, Alloy 317L offers higher creep, stress - to - rupture, and tensile strength at elevated temperatures than conventional stainless steels. It is a low carbon or "L" grade which provides resistance to sensitization during
welding and other thermal processes

317L Stainless Steel Pipes and Tubes Dimensions:
All Pipes is manufactured and inspected/tested to the relevant standards including ASTM, ASME and API etc.

 

General Properties

Alloy 317LMN and 317L are molybdenum - bearing austenitic stainless steels with greatly increased resistance to chemical attack as compared to the conventional chromium - nickel austenitic stainless steels such as Alloy 304. In addition, 317LMN and 317L alloys offer higher creep, stress - to - rupture, and tensile strengths at elevated temperatures than conventional stainless steels. All are low carbon or "L" grades to provide resistance to sensitization during welding and other thermal processes. The "M" and "N" designations indicate that the compositions contain increased levels of molybdenum and nitrogen respectively. The combination of molybdenum and nitrogen is particularly effective in enhancing resistance to pitting and crevice corrosion, especially in process streams containing acids, chlorides, and sulfur compounds at elevated temperatures. Nitrogen also serves to increase the strength of these alloys. Both alloys are intended for severe service conditions such as flue gas desulfurization (FGD) systems.
