317LMN Stainless Steel Plate

General Properties

Alloy 317LMN is an austenitic, higher-molybdenum bearing stainless steel further alloyed with nitrogen that is particularly effective in enhancing resistance to pitting and crevice corrosion and also has excellent resistance to chemical attack. Its low carbon composition provides resistance to sensitization during welding and the additional nitrogen serves to increase its strength. Alloy 317LMN has the highest aqueous corrosion resistance of all standard stainless steels and also has higher creep, stress-to-rupture, and tensile strength at higher temperatures.


Specifications: UNS S31726


Applications:

Similar to alloy 317L, 317LMN is commonly used to handle sulfur, pulp liquor, acid dyestuffs, bleaching solutions, flue gasses, and many chemical compounds. Industries that frequently use alloy Alloy 317LMN include:

  • Paper and pulp

  • Textile

  • Food processing

  • Process equipment


Standards:

  • ASTM/ASME: UNS S31726

  • EURONORM: FeMi35Cr20Cu4Mo2

  • DIN: 1.4439


Corrosion Resistance:

  • Alloy 317LMN, along with 317L, is considered more resistant to atmospheric and other mild type of corrosion, along with solutions of sulfuric acids, than conventional chromium-nickel stainless steels

  • Resistant to sulfuric acid concentrations at temperatures as high as 129oF (49oC)

  • High molybdenum and nickel content significantly improves chloride pitting and crevice corrosion

  • Low carbon content provides sensitization to intergranualr corrosion during welding and other thermal processes

  • Has the highest aqueous corrosion resistance of all standard stainless steels


Oxidation Resistance:

  • All chromium-nickel-molybdenum stainless steels have excellent resistance to oxidation

  • Has a low rate of scaling in ordinary atmospheres at temperatures up to 1600 to 1650oF (871 to 899oC)
