ASTM A815 S31803 Y-SHAPE TEE STAINLESS STEEL BUTT WELD FITTING B16.9
Y Type tee is a pipe fitting which can be produced in Butt Weld & Forged technique as per ASME B16.9 & ANSI B16.11. It is similar to a tee but has a side opening outlet branch at a 45 degree angle. We also call it from other names such as Y Tee Fitting， Y Shaped Tee， Y Cross Tee， Double Y Tee，Y Lateral Tee， Y Tee Pipe Branch Fitting etc. We at Neelcon can produce these Y Type Tee Pipe Fitting in Stainless Steel， Alloy Steel， Carbon Steel， Copper & Nickel Alloy Material.
Duplex stainless steel A815 UNS S31803 are extremely corrosion resistant， work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result， duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.
Duplex stainless steels A815 UNS S31803 are in most cases， tougher than ferritic stainless steels. Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels.
