Description

Duplex Stainless Steel UNS31803 2205 UNS32205 Pipe Eblow 90 Degree (LR) 1.5D Fittings

"Zheheng steel" is a professional manufacturer of UNS31803 2205 UNS32205 stainless steel pipe fittings and flanges,

Why use duplex steel 2205 and S31803 elbow fittings?
At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.
what is the Duplex 2205 pipe elbow fittings material?
Duplex 2205 pipe elbow fittings (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion.
