SDSS Buttweld Tee and Super Duplex Elbow manufacturer in India
Manufacturing Super Duplex Fittings as per ASME B16.9 American Standards, check SDSS Buttweld Fittings Price in India
A SDSS grade is designed with an austenitic and ferritic microstructure. The Super Duplex Pipe Fittings are designed with a superior chemical composition of nickel, chromium, and molybdenum. This content allows the fittings to showcase superior corrosion and oxidation resistance properties. These fittings play a pivotal role in influencing the characteristics of the flow in different conditions. Super Duplex Fittings possess good strength and have good resistance to stress corrosion at moderate temperatures when compared to austenitic grade steel. These fittings have enhanced resistance to crevice corrosion and pitting by acids in stress-induced setups. The super duplex stainless steel pipe fittings have a density of 7.8 g/cm3 with outstanding mechanical properties. These fittings may be slightly magnetic in certain conditions and possess an electrical resistivity of 8.12 μohm/cm. The versatile fittings are quality assured and manufactured by our renowned technicians with the best raw materials and latest technology.
The Super Duplex Elbow is a versatile fitting that is very common in this grade. These elbows play a pivotal role in changing the direction of the flow in the system. The elbows are designed with long or short diameter radiuses and are generally produced having 45 or 90-degree turns. All these fittings are available in different sizes and shapes to meet different customer requirements. Contact us if you are looking for super duplex pipe fittings manufacturers in India.

Hot forming of Super Duplex Pipe Fittings
SDSS Buttweld Fittings should be heat worked between 1875°F and 2250°F. After that, a solution anneal at a minimum of 1925°F and a fast air or water quench are required.
