Stainless Steel 304L Flanges

ASTM A182 F304L Blind Flange, SA 182 F 304L Stainless Steel Weld Neck, Slip On, Socket weld flanges manufacturer in India

Nitrogen enhanced stainless steel grades such as alloy 304L almost have similar levels of tensile properties to that of its original counterparts. Perks of using Stainless Steel 304L Flanges are not limited to only to its economical cost, but also includes its relative ease in weldability. The improved weldability is on account of the lowering of carbon content in the alloy. Typically a lowering the content of carbon eliminates the formation of carbide precipitates on the grain boundary. Hence, the chances for intergranular corrosion occurring in the ASTM A182 F304L Flanges are slim. Another fact that cannot be discounted is that even in the presence of severely corrosive compounds, these flanges could be used in an as welded condition. Manufacturers are also able to produce the ASME B16.11 Cl3000 A182 F304L Slip On Flanges, without the need of annealing the components.

However, annealing is required in those applications that mention or specify stress relieving. The mechanical properties of a UNS S30403 SS 304L Flange are slightly lower to that of grade 304. But, the addition of austenite balancing element such as nitrogen, improves these properties significantly, making up for the reduced carbon content. The corrosion resistance properties of both 304 & 304L are similar. Hence, the Werkstoff No 1.4301 304L Stainless Steel Flanges are well suited for applications in industries like chemical processing, dairy and food industry. The textile industry is known to make use of several harsh and corrosive chemicals to process materials. Since the production of textiles is very expensive, most manufacturers are in search of cost saving alternatives. Which is why using SA 182 F304L Blind Flanges is not only economical, but it also resistant to several chemicals, making it a commercially viable product.
