SMA is one of the best exporter, suppliers and stockiest of Stainless steel 321/ 321H flanges based in Mumbai, India. Stainless steel 321/ 321H flanges are made of using good quality raw material, which helps the customer use it for a longer period. Stainless steel 321/ 321H flanges are available in different sizes and shapes, and one can easily get it as per their own specifications. Stainless steel 321/ 321H flanges are best for heat resistance. Mostly it is used in the temperature range of 1000-1600F.

Titanium is the differentiating factor between stainless steel 304 & stainless steel 321, which further reduces carbide precipitation during welding. Stainless steel 321 slip-on flanges have the best oxidation-resistant up to 1600F. Stainless steel 321H weld neck flanges have the best intergranular corrosion as it is stabilized against the weld heat-affected zone (HAZ). Stainless steel 321 socket weld flanges also help to resist polythionic acid stress corrosion cracking. One of the main features of stainless steel 321 blind raised flanges is that it has excellent strength and better corrosion resistance. Stainless steel 321 lap joint flanges contain 18% chromium, 8%nickel, and the required portion of titanium.

Stainless steel 321 flanges are used in refinery equipment and high-temperature chemical process. Stainless steel 321H socket weld flanges are applied in expansion joints and thermal oxidizers. Stainless steel 321H lap joint flanges are used in aircraft piston engine manifolds and exhaust stacks. Stainless steel 321 threaded flanges are also used for power generation and petrochemicals. Stainless steel 321 flanges is used for seawater equipment and off-shore oil drilling companies.
