- Components Of SS 321/ 321H Flanges
It combines elements like carbon, manganese, silicon, phosphrous, sulfur, chromium, nitrogen, nickel and titanium alloy. It is stabilized austenitic stainless steel flanges with good general corrosion resistance. It shows excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation. These alloy resists oxidation to approx. Temp. Also, it has higher creep and stress rupture properties than other alloys.
Stainless steel flanges are shows a higher carbon version of the alloy. It was developed for enhanced creep resistance and higher strength. Alloy 321 stainless steel flanges cannot be hardened by heat treatment. It’s hardened only by cold working. It is also easily welded and processed by standard shop fabrication. These flanges are generally developed to supply a specific type of alloy but improved intergranular corrosion resistance.
- Properties Of SS 321/ 321H Flanges
The flanges show properties like excellent flexibility, durability, and weldability, making them suitable for a wide range of applications. The manufacturing process of these flanges is mainly divided into forging, casting, cutting and rolling.
Stainless Steel 321H Flanges is a titanium stabilized chromium and nickel. These flanges provide exceptional strength and durability. Flanges show great features like durable performance, excellent corrosion resistance, dimensional accuracy and minimum maintenance. The fabrication process of these flanges is carried out under packing, heating, pre-forging, drawing, cutting, trimming, blasting, etc.
