Super Duplex Steel Grades Plate 309S 4.0* 1500*6000mm Hot Rolled For Industry
Difference between 304 and 309
Alloy 309/309S is an austenitic heat resisting stainless steel. 23% chromium, approx. 5% more than 304 stainless steel gives Alloy 309/309S an edge over 304 stainless steel when it comes to general corrosion resistance at elevated temperatures.

Applications of duplex steel
Duplex steel is not only used in various industries such as pulp and paper, onshore and offshore oil and gas industry, chemical processing industry, transportation industry (chemical ships and tankers), pharmaceutical and food industry and construction industry, but also in reaction vessels, various industrial equipment and pipelines. In most applications, duplex stainless steel is considered to be a cost-effective material fills the ordinary austenitic stainless steel 316 austenitic stainless steel and high alloy such as the gap between although generally think that the use of duplex stainless steel because they have a corrosion resistant to chemical products, such as the production of urea and chemical fertilizers, organic acids and containing hydrogen sulfide gas processing encountered some interfaces But the most important applications are in hot water solution media containing chloride ions where austenitic stainless steel does not have sufficient resistance to pitting and stress corrosion fracture, such as heat exchangers, condensers and various vessels.
