Weldability of duplex stainless steels- A review

Duplex stainless steel finds widespread use in various sectors of manufacturing and related fields. It has many advantages due to its distinctive structural combination austenite ferrite grains. is the need current generation better corrosive resistance over high production austenitic steels. This paper reviews weldability duplex steels, mentions reason behind for steels describes how it came into existence. The transformations heat-affected zones during welding have also been covered this paper. formation, microstructure changes temperature low reviewed extensive detail. effects cooling rate on formation briefly discussed. A comparison between given. Finally, applications grades a variety industries like chemical, power discusses future scope industrial sectors.
