While the chemistry of Stainless Steel 304L Flanges is similar to grade 304, there are some changes done to its chemical composition. The modification in the chemistry of grade 304L improves its properties like weldability. The lowering of carbon content as well as the addition of nitrogen in the alloy of ASME B16.11 Cl3000 A182 F304L Slip On Flanges, is what brings about the changes in the alloy. Firstly, a low carbon content provides an ease with regards to welding. Therefore, the Werkstoff No 1.4301 304L Stainless Steel Flanges can be easily welded and processed by the most conventionally used shop fabrication practices. Furthermore, there is no sensitization of grain boundary precipitates, meaning the alloy of UNS S30403 SS 304L Flange has excellent resistance to intergranular corrosion.
Flanges produced under specification ASTM A182 Stainless Steel 304L Flanges are required to conform to the suggested heat treatment process, chemical composition as well as mechanical properties.
Hence it could be used in the as-welded condition. Known to be a versatile alloy, the SA 182 F304L Blind Flanges are relatively less expensive than grade 316, while offering good corrosion resistance properties, with medium to good tensile strength. ASTM A182 F304L Flanges has good resistance to atmospheric corrosion and is used in the food and beverage industry due to its resistance to several organic and inorganic chemicals in moderately oxidizing to moderately reducing environments.
