Duplex Steel stud bolts are kind of fasteners which is head less. This is a threaded bar or rod from one end to another or it may even be partially threaded as per it's relavent international standard or as per customer's specific requirement to suit the project or job.

 

Why Stud Bolts in Duplex Steel


Duplex steels studbolts are having the best maximum possible hardness comparing to other stainless steel grades. It is a metal of unique kind of hardness and mechanical properties. Duplex steel metal with standingg power against corrosive is also too good and at the same time in this metal nickel content which is the costliest metal in all stainless steel grades. So in short it makes the duplex stainless steel metals economical as welll as more reliable comparing to stainless steel studbolts.

Manufacturing process of Duplex Steel Studbolts

 

There is a huge variety of fasteners in duplex steel and it depends on type of fasteners you need to manufacture to adopt the manufacturing it. For example Studbolts is a kind of fasteners and for manufacturing it we need plain bar. There are two process to manufacture duplex steel Studbolts one is of thread rolling process and second is chezer threading. Second process is out dated and rarely sued while the first process is universally accepted and quality process.

 

Heat treatment of Duplex Steel Stud bolts

To manufacture duplex steel Studbolts are manufactured from the specific drawn sizes and not from either hot rolled wire or hot rolled round bars. This is a process of drawing and once it is drawn it not only becomes too hard but also its physical and mechanical properties gets changed and to normalize the same we have to undergo on operation known as heat treatment of duplex steel Studbolts.
