General Properties : Alloy 317L is 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, 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 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.
Resistance to Corrosion :

• Alloys 317L stainless steels is more resistant to atmospheric and other mild types of corrosion than conventional chromium-nickel stainless steels. In general, environments that are not corrosive to 18Cr-8Ni steels will not attack alloys containing molybdenum, with the exception of highly oxidizing acids such as nitric acid.
• Alloys 317L stainless steels is considerably more resistant than conventional chromium-nickel types to solutions of sulfuric acid. Resistance increases with alloy molybdenum content. These alloys are resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120^oF (49^oC). At temperatures under 100^oF (38^oC) these alloys have excellent resistance to solutions of higher concentration. However, service tests are recommended to account for the affects of specific operating conditions that may affect corrosion behavior. In processes where condensation of sulfur-bearing gases occurs, these alloys are much more resistant to attack at the point of condensation than conventional Alloy 316. The acid concentration has a marked influence on the rate of attack in such environments and should be carefully determined by service tests.
• The low carbon (less than 0.03%) of these alloys effectively prevents sensitization to intergranular corrosion during thermal processes such as welding or forging. The higher chromium contents of and Alloy 317L stainless steels also provide superior resistance to intergranular attack. It should be noted that prolonged exposure in the range 800 to 1400^oF (427-816^oC) can be detrimental to intergranular corrosion resistance and may also cause embrittlement due to precipitation of sigma phase.
• 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.

Physical Properties : The physical property data which follows represent the iron-chromium-nickel-molybdenum class of stainless steels. For all practical purposes, the data are applicable to Alloy 317L stainless steel. All properties are at room temperature (68°F, 20°C) unless stated otherwise.
