Duplex Stainless Steel Bolts Manufacturing Process :-

There is a huge variety of in duplex steel bolts category and it depends on type of bolts you need to manufacture, accordingly we need to adopt the manufacturing process best suitable and viable. For example Duplex Steel Heavy Hex Bolts is a kind of Bolt and for manufacturing it we need plain round bar. These type of bolts are needed to be manufactured by hot forging process only to save the material. After giving head shape machining process is there and at final stage threading, thread rolling process is done. Here also the bolt need to be given final finish according to the end application.


 

Quality Check of Duplex Steel Bolts :-

There are many points check while manufacturing to delivery of Duplex Steel Bolts. Since bolts can be manufactured in many ways the quality check of these fasteners will be accordingly.

Weather it is Duplex Steel Bolts or it is nickel alloy Hex Bolts or even stainless Bolts, the quality check for all the Bolts remains same. The first and foremost thing in quality check of these Bolts is uniformity of threading pattern so that the nuts or the object where these Bolts are suppose to be fitted should neither be loose nor there should be any problem while fitting it. There is international set norms to control threading quality by thread gauges, which simplifies manufacturer job as well as quality controller or inspectors job.
