DESCRIPTION
AISI 316L – is an austenitic stainless steel grade alloyed by Mo to increase resistance to pitting corrosion, non-oxidizing acids and chloride-containing media. It is characterized by has good formability and weldability.
The main application of AISI 316L – is tubes, boilers, flanges, valves, vehicle tanks, architectural decoration, food, pharmaceutical and textile industries, petrochemical and chemical applications, etc.
