Duplex 2205 Bolts

Duplex 2205 Hex Bolt and Duplex Fasteners manufacturer in India

Manufacturer and exporter of UNS S31803 Stud, Duplex Steel Threaded Rod and Hex Nuts in Metric and Unified Thread

Aesteiron Steels LLP, is one of the leading duplex fasteners manufacturer which find its application across diverse sectors. We are also duplex bolts suppliers which are readily available in the size range of M6 to M80 or ¼” - 4” in metric and imperial size manufactured by hot & cold forged.Duplex 2205 fasteners find it’s applications due to both excellent corrosion resistance and high strength. It is not suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents, nor below -50°C because of its ductile-to-brittle transition. Duplex Steel fasteners are used to joint one or more components, either permanently or non-permanently. There are different types of fastener, each with their own purpose. It is main components which are used in many sectors such as manufacturing, automation, infrastructure and others. 2205 duplex stainless steel fasteners are of three main types i.e threaded fasteners, bolts, screw and studs.duplex 2205 bolts are usually used to hold materials or objects together, or to position objects. It has various types of bolts such as blind bolts, anchor bolts, eye bolts, hex bolts, carriage bolts, machine bolts, etc. duplex stud bolts has the desirable properties of both austenitic and stainless steels, namely high strength; excellent corrosion resistance; resistance to stress corrosion cracking. duplex bolts & nuts are used to secure or fasten materials together. It is frequently chosen over regular ferritic or austenitic stainless steels due to its increased strength. It also exhibit better toughness and ductility compared to ferritic stainless steels. duplex hex bolt has hexagonal heads and machine threads. It is used with a nut or in a tapped hole. It is also called as hex cap screws. It has good high temperature oxidation resistance which suffers from embrittlement if held for even short times at temperatures above 300°C. Duplex 2205 Studs is essentially just a piece of threaded bar and in some cases, these are both intended to accept nuts such a stud is called a stud bolt. It possesses excellent corrosion resistance which is superior to stainless steel 316 in most environments. The advantage to choose duplex fasteners manufacturer is to get 10% lower price compare to stockist and supplier in Mumbai and Prime quality material with Mill test Certificate.
