Stainless Steel 321 Pipe Fittings
Manufacturer ASTM A403 WP321h Elbow, View Weight Chart UNS S32100 Buttweld Fitting
Grade 321 stainless steel is an austenitic alloy with the addition of titanium. The Stainless Steel 321 Pipe Fittings is developed with intergranular corrosion resistance. These 321 fittings are resistant to sterilizing solutions, corrosion, chemical, and other inorganic chemicals. The addition of titanium reduces the carbide precipitation during welding. As a result, the UNS S32100 Buttweld Fitting has good welding and formability properties. These fittings are a good choice in high-temperature environments of 800 °F and 1650 °F. They are commonly used in exhausts, aircraft collector rings, and high-temperature chemical equipment. We are one of the top Stainless Steel 321 Pipe Fittings manufacturers in India who focus on creating high-quality products at the most reasonable prices.

ASTM A403 WP321h Elbow
UNS S32100 Buttweld Fitting
Buy directly from SA403 WP321 Tee stockist, Top-notch supplier of WNR NR. 1.4541 Fittings
The ASTM A403 WP321h Elbow is used to change the angle of flow in pipelines. These ASTM elbows are advantageous because of their good mechanical properties as well as good performance under extreme temperatures. The WNR NR. 1.4541 Fittings are mostly used in building and chemical industries. They are manufactured with higher creep and stress rupture properties compared to 304 alloys. Our experienced workers use the best raw materials and the latest technology to produce the best products.
The ASME SA 403 WP 321 Pipe Reducer is designed with increased wall thickness. These thick walls provide it more durability as well as resists cracking due to high thermal stress from exhaust gases or rising temperatures. These reducers can be either concentric or eccentric. We also produce the SA403 WP321 Tee, which can be customized into different shapes and sizes to fit pipes or valves of different dimensions. If you have any questions about our products or prices, contact us for more information.
