Duplex Fasteners

 

Table Of Content

 

The Duplex 2205 Fasteners are made up of 2205 stainless steel, which is the mostly commonly used duplex grade. This is a nitrogen enhanced alloy of stainless steel, which comes with good corrosion resistance properties. They show good resistance to different types of corrosion even in welded conditions.

The Duplex Stainless Steel Fasteners possess high strength, which is why they are useful in many applications. But due to their increased hardenability, they have lower machinability. The strength of the Duplex Bolts material also makes it difficult to bend or form them, they require a larger capacity equipment than what is required for austenitic steel products.

The Duplex Hex Bolt material has good content of elements like chromium, molybdenum, and nickel in its chemical composition, which is why they show good pitting resistance. In fact the Pitting Resistance Equivalent (PERN) of the Duplex Threaded Rod is 35.8, which is quite high and exceeds that of 316 and 316L stainless steel grades. On heating, the microstructure of the Duplex Stud Bolts becomes such that it is a perfect mixture of the austenite and ferrite phases.

The microstructure of the Duplex 2205 Hex Bolt is also responsible for its high corrosion resistance capabilities in different types of environments. In fact, the Duplex 2205 Threaded Rod possesses superior corrosion resistivity than other stainless steel grades like 316 or 317.

The min yield strength of the Duplex 2205 Stud Bolts is basically more than double that of the conventional austenitic stainless steels. The microstructure and phase balance of Duplex 2205 Screw materials are designed in such a way that they facilitate production of various piping and tubing solutions.

Due to all the properties, the Duplex 2205 Heavy Hex Bolt is used in a wide range of industries like chemical processing, marine industry, paper and pulp industry, and many more. Clients should always buy Duplex 2205 Socket Head Cap Screws from renowned manufacturers, who offer quality products at a competitive price.
