ASTM A182 F304L Flange

At moderate temperatures, SS 304 flanges can also provide good performance in aggressive solutions, especially those that do not contain chlorides or fluorides. While Grade 304 performs well in fresh water applications with low chloride levels (i.e. less than 100 parts per million), exposure of the alloy to higher chloride levels makes UNS S30400 304 stainless steel flanges susceptible to crevice and pitting corrosion Impact.

There are different types such as A182 F304 SORF flange which is a slip on raised face flange. Slips on flanges are suitable for use with seamless pipe to create precise connection locations. The raised face of the flange provides an additional surface for welding or bolting. The SS 304 WNRF flange is a butt weld raised face flange. Raised faces help with connection, while welded necks provide extra grip to hold pipes in place. Flanges range in size from ?” to 48″ in diameter.

ASME SA182 304 stainless steel flanges have a minimum of 18% chromium, 8% nickel and a maximum carbon content of 0.08%. UNS S30400 SS flanges are defined as chromium-nickel austenitic alloys. Meanwhile, grade 304 is the standard “18/8” stainless steel you might see in pans and cooking tools. We supply these SS SUS 304 Pipe Flanges on custom request to our valued customers.

HT PIPE is one of the leading suppliers and traders of SS 304 flanges which are nickel plated to maintain austenitic composition at lower temperatures. Stainless Steel 304 Slip Flanges are austenitic stainless steel with better corrosion resistance than Stainless Steel 317.

Stainless Steel UNS S30400 Socket Weld Flanges also offer higher creep, rupture stress and tensile strength at elevated temperatures, excellent corrosion resistance and strength properties, making them ideal for manufacturing or forming applications.
