Duplex Steel Flanges

Duplex steel flanges have a yield strength approximately twice that of ordinary austenitic stainless steel flanges. They also possess a certain toughness, maintaining excellent structural strength and deformation resistance in high-pressure and high-temperature environments.

 Excellent Fatigue Resistance: Due to their high strength and optimized microstructure, duplex steel flanges exhibit excellent fatigue resistance under cyclic loading conditions, capable of withstanding multiple stress cycles without cracking, thus extending their service life.
 Excellent Weldability: While welding requires control of certain process parameters, such as heat input and interpass temperature, duplex steel flanges generally exhibit excellent weldability, enabling reliable connections through welding.
 Economical: Although the initial purchase cost of duplex steel flanges may be slightly higher than that of ordinary stainless steel flanges, their high strength allows for the use of thinner plate materials in designs, reducing material consumption. Their long service life and low maintenance costs also reduce overall project costs.
