Hunan Hemway Steel Co., Ltd.
Duplex stainless steel is known for its excellent corrosion resistance, high mechanical strength, and superior resistance to stress corrosion cracking. This is achieved by its microstructure, which is approximately 50% ferrite and 50% austenite, allowing it to combine the key benefits of both ferritic and austenitic stainless steels.
With nearly twice the mechanical strength of common stainless steel grades like 304 and 316, duplex stainless steel is gaining global popularity due to its cost-saving potential. This is achieved through reduced thickness requirements and lower overall lifecycle replacement costs, thanks to its outstanding corrosion resistance.
