HC550/980DP Duplex Steel is a high-strength, highly corrosion-resistant steel that offers many advantages over traditional stainless steels. The higher strength of HC550/980DP dual phase steel allows for thinner gauges and lighter components, while enhanced corrosion resistance ensures your products will last longer and perform better in even the most challenging environments good. In addition, HC550/980DP duplex steel is easy to weld and process, making it an excellent choice for a wide range of applications.
Microstructure of HC550/980DP ordinary cold-rolled DP steel: mainly ferrite and martensite, martensite is dispersed in the ferrite matrix in the form of islands, and softer ferrite can make the steel have good formability . Hard martensite can make steel have high strength. Strength increases with increasing proportion of martensite. Depending on the application, different yield strength ratios (YS/TS) DP steels are produced.
