Useful Information:

Key Properties of ASTM A182 F 317L Stainless Steel Flanges

• High corrosion resistance in tough environments
• Lower intergranular precipitation
• High resistance to pitting and crevice corrosion

Common Applications ASTM A182 F 317L Stainless Steel Flanges

• Pulp and paper manufacturing plants
• Chemical processing equipment
• Petrochemical processing equipment
• Textile machinery and equipment
• Vessels and tanks

317L is an molybdenum-bearing austenitic stainless steel, with greatly increased resistance to chemical attack as composed to the conventional chromium-nickel austenitic steel tubes as 304L & 316L. the addition of molybdenum gives alloy 317L tubing improved resistance to chloride and other halides. Due to its low carbon content the 317L tubing can be welded without risk of sanitization due to inter granular corrosion that can result from chromium carbide precipitation in the grain boundaries. 317L is non magnetic in the annealed condition, but may become slightly magnetic as result of welding.

Technical details

High molybdenum and nitrogen contents can significantly improve pitting resistance as illustrated in the preceding table of Pitting Resistance Equivalents (PRE). The PRE is based on the results of corrosion tests in which it was found that nitrogen was 30 times more effective than chromium and approximately 9 times more effective than molybdenum in enhancing chloride pitting resistance.

The temperature of the onset of crevice corrosion as determined in a modified AST G-48B test is a useful means of ranking the relative resistance of stainless and nickel-base alloys. The Critical Crevice Corrosion Temperatures table that follows demonstrates that crevice corrosion resistance for austenitic stainless steels increases with the alloy’s molybdenum and nitrogen content.

*72-hour exposure based on ASTM G-48B procedure using the following solution:
7 vol.%H2SO4, 3 vol%HCI, 1 wt% CuCl2, 1 wt%FeCl3
Oxidation Resistance
The chromium-nickel-molybdenum steels all have excellent resistance to oxidation and a low rate of scaling in ordinary atmospheres at temperatures up to 1600-1650 °F (871-899 °C).
Fabrication
The physical and mechanical properties of 317LMN and Alloy 317L stainless steels are similar to those of more conventional austenitic stainless steels and can, therefore, be fabricated in a manner similar to Alloys 304 and 316.
