N.R. Engineering is one of the leading duplex fasteners manufacturer which find its application across diverse sectors. We are also Duplex Studs suppliers which are readily available in the size range of M6 to M80 or ?? – 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. Duplex stud has the desirable properties of both austenitic and stainless steels, namely high strength; excellent corrosion resistance; resistance to stress corrosion cracking. Duplex Studs 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. It is used with 2 nuts. 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.
