What is Stainless Steel 321/321H Flanges ?
Alloy 321 flanges are stabilized austenitic stainless steel with intergranular corrosion resistance. These flanges are highly alloyed and made from high quality raw material and superior machineries. These flanges are available in various sizes and shapes. The sizes of the flanges range from ½” to 60”. The Stainless Steel 321 flanges are made with high quality combinations and elements.
The grade includes a high amount of 18% chromium and 8% nickel content. The grade also involves a considerable amount of titanium grade. The stainless steel 321-321H also has great weldability and annealing properties. Stainless steel 321H flanges are used as a boiler and heat exchangers in some industries.
Stainless steel 321H flanges can withstand high heat and cold temperatures. It also provides excellent resistance from corrosion, crevice corrosion and stress cracking. It also provides excellent protection from oxidation and cryogenic corrosion.

Stainless steel 321H flanges resists oxidation to 1500°F., which is why the creep and rupture strength of the grade is higher than other grades. Alloy 321H also has high carbon content which provides it an amazing resistance. The tensile and yield strength of this grade is higher than other alloys. The minimum tensile strength of this alloy is 75000 psi and the yield strength is 30000 Psi.
