The Duplex Steel 2304 Coils have a very composed and stable chemical and mechanical structure compared to the duplex stainless steel grades that include molybdenum in their chemical composition. These Duplex Steel 2304 Coils contain an equivalent concentration of the ferritic and austenitic elements in their chemical mixture after annealing is followed on the DS 2304 Coils at moderate temperature ranges. Being quite higher on the chromium levels, about 23%, the resistance offered by the DS 2304 Coils against corrosion caused by the general reasons is excellent and is headed equally to the Stainless Steel 317L grade.
Since the DS 2304 grade has a double microstructure consisting of lower nickel and elevated chromium contents, the DS 2304 grade and all its products, like the DS 2304 Coils, display an extremely great property of resistance against stress corrosion. This property of stress corrosion resistance that the DS 2304 grade possesses is more improvised than what the Stainless Steel 304L, Stainless Steel 316L grade, and the other austenitic standards contain.

The DS 2304 Coils have always proven their superiority and outdone the stainless steel grades of 304L and 316L in terms of characteristics like resistance against stress corrosion cracking when used in the chloride solutions of liquid form. The corrosion rate of duplex steel 2304 presented in nitric acid while boiling is 65% higher than that of stainless steel 316L grade in the same acid. The escalated values of DS 2304 Coils’ yield strength offers them to function well in abrasion applications.
