317L Stainless Steel Plate - LM / LMN- UNS S31703, S31725, S31726


317L/LM/LMN are low-carbon, higher molybendum austenitic stainless steels with higher nickel alloy content.  Developed to resist the attack of sulfuric acid compounds, these alloys combine good corrosion resistance with good mechanical properties and fabricability.  They are frequently used for flue gas desulfurization service.
