317LMN Stainless Steel Tube
Alloy 317LMN (UNS S31726) is an austenitic chromium-nickel-molybdenum stainless steel with corrosion resistance superior to 316L and 317L.
It is a higher molybdenum austenitic stainless steel alloyed with nitrogen the higher molybdenum provides the alloy enhanced corrosion resistance,
mainly in acidic chloride containing service.

Description
Product information
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.
