Stainless steel threaded en 10204 type 3.1 316 filter gasket elbow sus ss 304 flanges
Stainless Steel SS UNS S30400 Flange is a high corrosion resistant steel, it is an austenitic stainless steel with higher corrosion resistance than Type 316l or grades and Type 317l. Due to the addition of some elements, this material has excellent corrosion resistance to reducing acids such as sulfuric acid. It is used in plants and is widely used in a variety of different types of applications
ASTM A182 F304 Flange Chemical Composition And Mechanical Properties Of DIN 1.4301 SS 304 Flanges
Stainless steel 304 S30400 flanges are easy to weld and provide a strong welded connection in petrol and fresh water tanks. SS 304 flange comes in handy if temperature fluctuations are part of the production process. At the same time, SS 304 flanges are considered to be 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 1.4301 stainless steel flanges to intergranular corrosion. This composition makes the SS 304 flange strong and corrosion resistant for general corrosion service.
Regarded to be the most basic stainless steel, the SS 304 flange are also known as 18-8 grade with a higher content of chromium and low carbon content. The presence of low carbon content in the alloy restricts the formation of carbide precipitates during welding along with minimizing the 304 Stainless Flanges from being susceptible to intergranular corrosion. The high chromium content in the alloy provides the ASME B16.9 Sa 182 Gr F304 BLRF Flanges with resistance to oxidizing solutions such as nitric acid up to 55% weight and up to a temperature of 176°F. Flanges made from alloy 304 is also known to resists moderately aggressive organic acids like acetic acid. The nickel present in the alloy is what provides resistance to the ASTM A182 Gr F304 Flange in moderately reducing solutions for e.g. in pure phosphoric acid, whatever the concentration, in cold solutions as well as up to 10% diluted hot solutions.
