Product Description

PMI Tested A815 S31803 Duplex Stainless Steel Tee 

UNS S31803 has a high content of chromium, making the equal tee has good corrosion resistance. Even in chloride and sulphide environments, it exhibits very high resistance to stress corrosion cracking. But it will causes embrittlement at temperatures over 300°C.

Besides, UNS S31803 Equal TEE has good strength and elongation. And at low temperature, its notch ductility is better than ferritic and martensitic grades. Its working temperature at least is -50°C.

So this kind of stainless steel fittings is ideal for low temperature applications.

Duplex Steel Butt Weld Fittings are typically used in:

• Chemical processing, transport and storage
• Oil and gas exploration and offshore rigs
• Marine environments
• Pollution control equipment

Equal Tee begins as cast material, then rolled to the shape after reheating. This process is wrought. Most Butt Weld Fittings is also wrought fittings. So, UNS S31803 Equal Tee is one type of ASME B16.9 Butt Weld Fittings.
