Duplex Steel Fasteners

Duplex Steel Fasteners are kind of Stainless steel fasteners with best maximum possible hardness in stainless steel. We got good name in the market for the variety of duplex stainless steel fasteners as well as design. These fasteners are made according to the industrial norms and well cleared with quality levels. As the components designed and well checked by experienced engineers and maintained accurate, sturdiness, anti-corrosion etc. so can be used without any problems.

What is Duplex Steel Fasteners

Duplex stainless steels Fasteners have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60.

Applications of Duplex Steel Fasteners

Duplex Steel Fasteners are widely used in Oil and Gas industries, Construction Industries, Offshore Industries, On Shore Industries etc. The demand for Duplex Steel fasteners are increasing day by day because of its characteristics.

Dimensional Standards Applicable for Duplex Steel Fasteners

DIN Standard Duplex Steel Fasteners
ANSI Standard Duplex Steel Fasteners
BS Standard duplex steel Fasteners
ISI Standard Duplex Steel Fasteners
ISO Standard Duplex Steel Fasteners

Why Duplex Steel Fasteners Used?

Duplex stainless steels Fasteners have roughly twice the strength compared to austenitic stainless steels Fasteners and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. Duplex Steel Fasteners containers high chromium (19–28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels.

Duplex grades are characterized into groups based on their alloy content and corrosion resistance. Lean duplex refers to grades such as UNS S32101 (LDX 2101), S32304, and S32003. The standard duplex is 22% chromium with S31803/S32205 known as 2205 being the most widely used. Super duplex refers to 25% chromium grades such as S32760 (Zeron 100), S32750 (2507), and S32550 (Ferralium). Hyper duplex refers to higher chromium grades such as S32906. The properties of duplex stainless steels are achieved with an overall lower alloy content than similar-performing super-austenitic grades, making their use cost-effective for many applications.

Our product range is vast and there is genuine reason behind the same and that is we are not manufacturing All of them either under one roof or even All in house which help us to get the final end product at the most economical price with world class quality norms too with our strict parameters of quality process.

Manufacturing process of Duplex Stainless Steel Fasteners

There is a huge varity of fasteners in duplex steel and it depends on type of fasteners you need to manufacture to adopt the manufacturing it. For example stud bolts is a kind of fasteners and for manufacturing it we need plai bar. There are two process to manufacture duplex steel stud bolts 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.
