Question 1

What are Duplex Fasteners and why are they used?

Accepted Answer

Duplex fasteners are made from duplex stainless steel, a combination of austenitic and ferritic structures, giving them both high tensile strength and excellent corrosion resistance. They are used in applications where standard stainless steel fasteners fail, such as marine, chemical processing, offshore platforms, and industrial infrastructure. Their dual phase composition allows them to resist stress corrosion cracking, pitting, and crevice corrosion while maintaining structural integrity under heavy loads.

Question 2

What industries commonly use Duplex Fasteners?

Accepted Answer

Duplex fasteners are widely used in the oil & gas, petrochemical, chemical processing, offshore engineering, power generation, and heavy construction industries. They are especially valuable in environments with high chloride exposure, seawater contact, or acidic conditions, where standard stainless steel or carbon steel fasteners would corrode or fail prematurely.

Question 3

What are the advantages of using Duplex Fasteners in marine applications?

Accepted Answer

In marine and offshore environments, Duplex Fasteners resist saltwater corrosion, pitting, and crevice corrosion, ensuring long term joint integrity. Their superior mechanical strength allows them to withstand wave action, vibration, and high stress, making them ideal for shipbuilding, offshore platforms, desalination plants, and coastal infrastructure projects.
