Stainless Steel 304 Flanges

Stainless Steel 304 Flanges

Stainless Steel 304 Flanges, also known as 18-8 grade, have a higher chromium content and a low carbon content. The alloy’s low carbon content limits the formation of carbide precipitates during welding while also making 304 Stainless Flanges less susceptible to intergranular corrosion. Because of the alloy’s high chromium content, the ASME B16.9 Sa 182 Gr F304 BLRF Flanges are resistant to oxidizing solutions such as nitric acid up to 55 percent weight and up to 176°F. Alloy 304 flanges are also known to be resistant to moderately aggressive organic acids such as acetic acid. The nickel in the alloy is responsible for the ASTM A182 Gr F304 Flange’s resistance in moderately reducing solutions, such as pure phosphoric acid at any concentration, in cold solutions, and up to 10% diluted hot solutions.

Stainless steel 304 applications:

  • Grade 304 pipe flanges are used in the chemical industry. In the plumbing industry, stainless steel flanges are used.
  • Power plants use forged stainless steel flanges, whereas the paper and pulp industries use 304 stainless steel flanges. Stainless steel flanges are used in a variety of applications.
  • In the fabrication industry, Stainless Steel 304 Industrial Flanges are used.
  • Stainless steel 304 flanges are used in the food processing industry, while ANSI Stainless Steel 304 flanges are used in a structural pipe.
  • High-grade Monel alloy is used to make the pipes and tubes.

How many types of 304 flanges are there?

The welding neck, long welding neck, slip-on, socket weld, lap joint, threaded, and blind flanges are the most common types of Stainless Steel 304 flanges. Besides from standard flanges, there are also some special flanges which include Weldoflange/Nipoflange and Elboflange, swivel flange, expander/reducer flange, and orifice flanges.

What is ASTM A182 304 SS Flanges?

The 300 Series Stainless Steel austenitic SS 304 Flanges conforms to ASTM A182. A minimum of 18% chromium, 8% nickel, and a maximum of 0.08 percent carbon are included in ASME SA182 304 stainless steel flanges. Chromium-Nickel austenitic alloy is the definition of UNS S30400 SS Flanges.
