ASTM A182 F316L

A derivative of grade 316 stainless steel, grade316L is an alloy whose chemistry is almost similar to that of the former metal, save for the reduction of carbon content in its alloy. The significant reduction in the content of carbon in the ASTM A182 F316L Flanges is what yields high compatibility with welding and eliminates intergranular corrosion caused by sensitization of grain boundary precipitates. However, the low content of carbon also indicates that alloy grade 316L has a low structural strength. Which is why manufacturers producing the ASTM A182 GRADE F316L WNRF Flange remedy this problem by the addition of element nitrogen in its alloy.

Nitrogen in any austenitic stainless steel component such as the Inox 316L Slip On Flange not only increases austenite stability, but the yield strength is also increased. Grade 316L Stainless Steel Flanges are also referred to as marine grade steel and hence is used in applications like marine engineering which requires welding operations to be performed. Adding nitrogen also improves the pitting resistance of the alloy, while ensuring the mechanical properties of SS 316L Blind Flange are almost at par with the conventional alloy, grade 316. In comparison to chromium-nickel based austenitic stainless steel grades, the molybdenum bearing ASME SA182 F316L Pipe Flange offers higher creep, stress to rupture as well as tensile strength at high temperatures. The addition of molybdenum gives Stainless Steel 316L Flanges better overall corrosion resistant properties, particularly higher resistance to both pitting and crevice corrosion in chlorine containing environments.
