What is Duplex 31803 Fasteners ?

The Duplex 31803 Fasteners are characterized by austenitic and ferritic nature. The chemical composition of this alloy consists of nickel as well as molybdenum along with chromium. This combination gives the alloy great tensile strength. These fasteners are resistant to corrosion-related corrosion cracking and corrosion pitting.

These Duplex 31803 Fasteners can also withstand chlorine bound environments and are therefore used widely in seawater as well as the off the shore applications. These fasteners also possess the property of being weldable. These fasteners can also withstand various acidic mediums such as hydrochloric acids as well as sulfuric acids. These fasteners also have great mechanical as well as chemical characteristics and can withstand temperature that is elevated.
