Grades SS A182 f321 flanges is a basic austenitic grade 18/8 steel that has been stabilized by the addition of Titanium (321). Grade 321 stainless steel is similar to 304 in terms of its chemical composition, with the only difference being in the addition of titanium. This ASTM a182 f321 grades are used as they are not sensitive to intergranular corrosion after being heated in the carbide precipitation range of 425 °C - 850 °C. The ASTM a182 f321 is the ideal grade of choice for applications that involve being used at an elevated temperature range of up to about 900 °C. Besides being able to withstand high temperatures, the stainless steel 321 flanges have high tensile strength. They also offer good resistance to scaling as well as phase stability with resistance in subsequent aqueous corrosion. Grade 321H stainless steel is a modification of the 321 stainless steel flanges reducing with a higher carbon content as compared to the former. This modification on the 321 stainless steel flanges suppliers has been done to provide improved high-temperature strength. A limitation faced by the 321 ss flanges is that titanium does not transfer well across a high-temperature arc. Hence, it is not recommended to be used as a welding consumable. The most commonly used 321 stainless steel flanges dimensions are the ASME/ANSI B16.5. The pressure for 321 stainless steel flanges ratings ranges between 150lb to 2500lb. The 321 stainless steel flanges manufacturers in India, supply these 321 stainless steel flanges to a variety of industries such as Petroleum, Chemical, Power, Construction, Gas, Metallurgy, and Shipbuilding
