tri clamp stainless steel 304 flange
304 stainless steel flanges are considered the most basic stainless steel, also known as grade 18-8, with higher chromium content and lower carbon content. The presence of low carbon content in the alloy limits the formation of carbide deposits during welding while minimizing the susceptibility of 304 stainless steel flanges to intergranular corrosion.
The high chromium content in the alloy provides the ASME B16.9 Sa 182 Gr F304 BLRF flange with resistance to oxidizing solutions such as up to 55% nitric acid by weight and temperatures up to 176¡ãF. Flanges made of Alloy 304 are also resistant to moderately corrosive organic acids such as acetic acid. Nickel in the alloy provides support for ASTM A182 Gr F304 flanges in moderately reducing solutions, such as pure phosphoric acid, regardless of concentration, in cold solutions as well as in dilute hot solutions up to 10%.
