The Duplex Bolts S31803 also have good fatigue resistance and corrosion resistance to most environmental conditions. There are different type of fasteners such as the Duplex Hex Head Fasteners and others. All the fasteners in this grade also have better thermal expansion values that allow these to be used under high temperatures. The applications of the UNS S31803 Fasteners include oil and gas, pulp and paper, sea water, subsea, marine and chemical applications. There are super duplex, lean duplex and standard duplex grades in the Duplex Stainless Steel Fasteners, each with specific properties that suit different applications. The material make or the composition differs but all duplex contains chromium, nickel and molybdenum in the composition. The Duplex 2205 Studs are some of the most used in terms of material grade. This is a standard duplex grade and is economically efficient than most other duplex grades. The UNS S31803 Bolt is produced in different dimensions and sizes from us. Regal Sales Corporation is a leading Duplex 2205 Fasteners manufacturer and supplier. The dual phase nature of the duplex steels prevent the grain growth in annealing procedures. Please feel free to contact us to know more about the duplex grades and the different types of fasteners such as the Duplex 2205 Nut Bolts.

Duplex 2205 Hex Bolts
Duplex Bolts are used in critical applications where the strength and corrosion resistance are equally important and cannot be compromised. The Duplex 2205 Hex Bolts can also get better strength than the ordinary stainless steels after strain hardening. The material is also ductile and can be used with better elongation than most other steel grades.
