ASTM A815 UNS S31803-S Duplex Stainless Steel Reducing Tee B16.9 For Desalination

A pipe fitting is used to change the direction of the pipe. The simplest way to do is to bend the pipe. However， it will stretch and thin out the outer walls of the pipe. It will also thicken the inner wall of the pipe. UNS S31803 duplex stainless steel fittings are wellknowned for having austenitic and ferritic microstructures. They display the properties of both classes. Improved localized corrosion resistance is displayed by ASME SA815 Duplex Steel Butt Weld Pipe Fittings.

 

The ASTM A815 UNS S31803 butt weld pipe fittings consist of duplex stainless steel， with equal portions of austenite and ferrite microstructure. The UNS S31803 Pipe Fittings has two phases and comprises ferritic， austenitic， 22 % chromium， 3 % molybdenum， 5 to 6 % nickel alloyed stainless steel. ASTM A815 UNS S31803 Duplex Stainless Steel Reducing Tee is said to have amazing toxic resistance and elasticity due to which they are used in the gas desulfurization industry.
