Duplex Steel Round Bars

 

duplex stainless steel bright bars
We are India based one of the leading manufacturers and suppliers of duplex steel Rounds Bars. Let's understand what duplex steel round bar is and why it is been chosen by engineers for their various project applications. Duplex stainless steels (DSS) round bars are widely used in petrochemical projects, chemical plants, cellulose and nuclear plants across the world directlyy or indirectly because of it's excellent austenitic-ferritic microstructure which in due offer an excellent combination of mechanical and corrosion resistance properties.

Many researchers have studied on duplex steel round bars and developed methods of detection and quantification of thermal embrittlement. Duplex steel round bars are excellent corrosion resistant in nature. These bars have high resistance to intergranular corrosion as well and even in chloride and sulfide environments, duplex steels round bars exhibit very high resistance to stress corrosion cracking. There is one more superior varsion of round bars in duplex steel alloy and i.e. super duplex steel round bars, these super duplex graded round bars are even more resistant to corrosion conditions.

The high chromium component in duplex steel round bars that protects against corrosion causes embrittlement at temperatures above 300° Celsius temperature. At low temperatures duplex steel round bars have better ductility than the ferritic and martensitic steel round bars. Duplex steel round bars can easily be used down up to at -50° Celsius temperature. Fabrication of all duplex steel round bars should be done only with tools dedicated to duplex steel materials. Tooling and work surfaces must be properly cleaned before it's use. These precautions are necessary to avoid cross contamination of duplex steel round bars by easily corroded metals that may discolour the surface of the fabricated product. Hardening by heat treatment of Duplex steel round bars can not be done. However it can be work hardened. annealing or Solution treatment can be done by rapid cooling after heating duplex steel round bars up to 1100° Celsius temperature.

Duplex Steel Round Bars are been manufactured from duplex steel con casted billets (RCS) by hot rolling process as usual as what it is being done in the process of other allys like stainless steel round bars or alloy steel round bars. This type of bars common and called as rooled duplex stainless steel round bars, in trading business it is also called as duplex steel black bars..

duplex steel peeled round bars Duplex steel bars which are oftenly bigger in size and or can not be either drawn or less in quantity to be produced and in this case we can supply our valued customer duplex steel peeled round bars. This is kind of duplex stainless steel bright round bars.

 

 

duplex steel forged round bars Duplex steel bars which are bigger in size and or can be either not rolled or less in quantity to be produced and in this case we can supply our valued customer duplex steel forged round bars. These round bars technical specifications gets changed because of forging pprocess.

 

 

Duplex steel black bars Duplex steel black bars are nothing but as rolled bars in duplex steel metals. We are manufacturers and suppliers of following grade round bars.

  • UNS S31803 Duplex steel black bars.
