What is Stainless Steel 321 Pipe Fittings?
The Stainless Steel 321 material offers excellent resistance to intergranular corrosion when exposed to the chromium carbide precipitation temperature range of 427 to 816 degrees C. Due to the presence of titanium in the chemical composition, the Stainless Steel 321 Pipe Fittings are quite stabilized against the chromium carbide formation. The Stainless Steel 321 Pipe Fittings also have an advantage when it comes to high temperature services. They possess high mechanical properties and have high stress rupture properties and creep strength compared to the 304 and 304L material grade.
The Stainless Steel 321 Pipe Fittings can be hardened only by cold working and no treatment should be used on it. It has high weldability and fabricability. Due to all these properties, they are used for a wide range of applications across several industries. They are especially used in environments that are highly corrosive.
UNS S32100 Short Radius Elbow Vs ASME SA403 WP321H Long Radius Elbow
The main difference between the UNS S32100 Short Radius Elbow and the ASME SA403 WP321H Long Radius Elbow is in their radius of curvature. For short radius elbow, the radius of curvature is equal to the diameter of the pipe, whereas for long radius elbow, the radius of curvature is 1.5 or more times the diameter of the pipe. While the short radius elbow is capable of giving a sharper turn, the long radius elbow offers less frictional resistance to the fluid.
ASTM A403 WP321H Buttweld Fittings and ASTM A182 F321 Forged Fittings
Stainless Steel 321 Fittings Vs 321H Stainless Steel Fittings
The Stainless Steel 321 Fittings has the austenitic stainless steel alloy which is titanium stabilized. They have good corrosion resistance properties. It also shows good intergranular corrosion resistance after getting exposed to a temperature, within the range of 427-816 degrees C. This is the chromium carbide precipitation range
The 321H material is a higher carbon version of the Stainless Steel 321 material. It has an enhanced creep resistance and possesses higher strength at a temperature above 537 degrees C. In most of the cases the carbon content of the Stainless Steel 321H Fittings is such that it gets dual certification.
