SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]
The nickel content in stainless steel UNS S30400 blind flanges prevents equipment corrosion from the use of acidic solutions, including acetic acid and phosphoric acid, which is a reducing acid.
The stainless steel 304 flange makes it easier to use in systems that require welding.
ASTM A182 F304 Stainless Steel Flanges are manufactured in accordance with ASME B16.5 150#, 300#, 600#, 900#, 1500#, 2500#.
With this high melting point, the flange can withstand temperatures up to 870 degrees Celsius. There are different types of flanges according to the face type. 304 stainless steel flanges are available with flat, raised and ring joints.
