LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
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.
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.
The nitrogen content of 317LMN acts as a strengthening agent giving it a higher yield strength than 317L. 317LMN is also a low carbon grade which enables it to be used in the as-welded condition free from chromium carbide precipitation on the grain boundaries.

The properties of 317LMN is similar to other conventional austenitic stainless steels, and can therefore be fabricated in a manner similar to alloys 304 and 306. The alloy is machined using heavy feeds and slow speeds and welded using all common methods. The material is initially forged at temperatures ranging from 1150 to 1205°C (2100-2200°F). It is then annealed at 1080 to1175°C (1975 to 2150°F) followed by air cooling or water quenching. The alloy can be hardened only by cold working.
