What is Duplex 2205 Fasteners ?

Duplex 2205 Fasteners are made up of an alloy with a higher content of chromium and either low or a moderate amount of nickel. This alloy is characterized by balanced austenitic as well as ferritic characteristics. The chromium content in this alloy allows them to be strong and gives them an excellent tensile strength.

The Duplex 2205 Fasteners are less likely to get damaged because of their tensile nature. The austenitic part gives them strength, whereas the ferritic nature gives them toughness. These fasteners help to reduce the overall weight of the structure to be manufactured, and hence this in turn also reduces the price of the structure, making these fasteners cost-friendly.

Sumit Impex focuses on manufacturing excellent quality Duplex 2205 Fasteners. These fasteners work very well in chlorine-bound environments and are resistant to corrosion-related corrosion pitting and corrosion cracking. As these fasteners are lighter in weight, they can be used in a large number of applications; however, this does not reduce the overall performance that these fasteners could possibly offer.

These fasteners work even more efficiently than the other austenitic stainless steel fasteners. The chemical composition of this alloy consists of chromium and nickel along with nitrogen and molybdenum. This combination helps to improve the mechanical strength of the fasteners. These fasteners could withstand a temperature up to 300 degrees celsius. However, if the temperature exceeds this particular limit, it may lead to the embrittlement of the fasteners.
