A182 F316L special flange primarily composed of iron and carbon
Type 316 stainless steel is manufactured into another grade due to its wide range of potential and is distinguished by the use of the letter “L” in its name. L represents the low carbon content in the steel.
316 and 316L are austenitic alloys, which means that these stainless steel products achieve corrosion resistance through the use of iron carbide or a non-magnetic solid solution of carbon in iron during the manufacturing process. In addition to chromium and nickel, these alloys also contain molybdenum, which also makes them more resistant to corrosion. 317L has higher corrosion resistance where the molybdenum content is increased from 2% to 3% in 316 and 316L to 3% to 4%.
