Table of Content


Duplex Steel Fixings or fasteners can be used to create non- permanent joints. A non- permanent joint is one which could be removed or dismantled without causing any damage to the joining components. Stainless steel Duplex Fasteners have a dual microstructure which combine aspects of ferritic and austenitic or martensitic grades together. The resultant duplex stainless steel alloy have been designed to demonstrate a favourable combination of the parent grade properties. For instance, the austenitic -ferritic microstructure based duplex stainless steels tend to have a higher tensile strength as well as better toughness as compared to ferritic grades. Further these Duplex Stainless Fasteners are not susceptible to stress corrosion related cracking and can achieve better resistance to pitting and can be welded relatively easily. On the downside, the resistance of duplex stainless steel to crevice corrosion is poorer as compared to either the ferritic or austenitic grades, which have similar levels of chromium and molybdenum content in their alloy.

Typically, Duplex Steel Fasteners are widely used in applications involving the highly demanding oil, gas, paper and petrochemical industries, although they are used in many more traditional applications, where the use of these fasteners have been less well known. However, increases and fluctuations in the price of nickel along with the availability of the  so-called lean duplexes has meant that these lean Duplex Fasteners  could be more cost effective to use, as opposed to a lower performing duplex grade. Typically Duplex Fasteners Manufacturer recommend using this alloy to the more conventional and familiar austenitic stainless steel grades, even for applications like  the reinforcement of bars for concrete.

Duplex Stainless Steel Fasteners are famous for its excellent combination of good mechanical properties and its high resistance to corrosion. Which is why these fasteners are widely used in various industrial fields. For example, stainless steel Duplex Fasteners are used in the production of seawater heat exchangers as well as in the chemical containers, which are exposed to high concentration of chloride containing environments.

Duplex stainless steel bolts will have less contents of both nickel as well as molybdenum as compared to their austenitic counterparts which offer similar levels of resistance to corrosion. Duplex grade stainless steel bolts, studs or screws are generally offered at a lower cost due to the lower alloying content i.e. Duplex Fasteners  are also referred to as DIN 1.4462. To illustrate, in comparison to those fasteners produced from grade 316 stainless steel these Duplex grade Stainless Steel Fasteners have higher resistance to corrosion. The mechanical properties of 2205 grade Duplex SS Fasteners is almost double as compared to SS 316 grade Bolts. Hence, fasteners such as Duplex  stainless steel Nuts, Duplex Steel Bolts, Duplex grade Washers, Duplex grade Screws as well as Duplex grade stainless steel Studs are mostly likely to be used in marine environments and in the oil and gas exploration industry.
