What are Duplex 2507 Bolts?

A duplex stainless steel alloy is used to make Duplex 2507 bolts, a high-strength fastener type. This special alloy comprises both austenitic and ferritic materials, giving it enhanced strength compared to similar alloys. The fasteners offer superior corrosion resistance and good formability due to their higher chromium, nickel, and molybdenum content levels. Many industrial applications typically use these fasteners where strength and corrosion resistance are crucial for success. It is common to find these products used in constructing oil platforms, bridges, ships, power plants, chemical plants, and other types of structural uses due to their great performance capabilities under tough conditions.

Uses of Duplex 2507 Bolts

Duplex 2507 bolts are super duplex stainless steel that is extremely corrosion-resistant and strong. You can use these bolts in various applications, particularly those requiring high temperatures and involving corrosive environments, such as oil rigs, marine construction, heat exchangers, desalination systems, chemical processing plants, pressurized tanks, and piping systems. People use them in bridges and offshore structures because of their durability and strength. Additionally, these bolts can be useful for structures exposed to cyclic stress due to their superior fatigue strength combination at higher temperatures than austenitic grades.

Corrosion Resistance

One of the most significant advantages of Super Duplex 2507 bolts is their excellent corrosion resistance, particularly in seawater environments. The duplex structure of these bolts makes them highly resistant to pitting, crevice corrosion, and stress corrosion cracking.

This resistance helps extend the service life of the bolts and reduces the likelihood of failure and safety hazards. Additionally, the corrosion-resistant properties of this product make them ideal for offshore and marine applications.

Strength and Durability

Super Duplex 2507 bolts have a higher strength and better durability than other bolts, thanks to their chemical composition combination of chromium, molybdenum, and nitrogen. Manufacturers build them to withstand harsh and challenging seawater applications, which can be incredibly corrosive.

This increased strength and durability help ensure that the Super Duplex 2507 bolt provides reliable and long-lasting support for critical structures, such as oil rigs, pipelines, and marine vessels.


Their excellent corrosion resistance and durability help reduce the cost of maintenance and replacements, as they don’t have to be replaced frequently. Additionally, 2507 Super Duplex bolts with a higher grade provide more robust strength and better performance, which can reduce the total number of bolts required for a project. This, in turn, saves on costs and time since fewer bolts need to be installed.

Availability and Compatibility

Super Duplex 2507 bolt is widely available in offshore, marine, and oil and gas applications. As such, they are easy to source and compatible with other materials used in seawater applications.

This compatibility makes 2507 Super Duplex bolts a convenient choice for contractors and engineers, as they can easily integrate them into a project. Additionally, their widespread usage and availability make for accessible and reliable support for any marine or offshore structure.


Super Duplex 2507 bolts offer numerous advantages, making them perfect for seawater applications. Their exceptional corrosion resistance, strength and durability, cost-effectiveness, availability, and compatibility have made them a popular choice for offshore, marine, and oil & gas applications. They are the right choice if you are working on a project requiring seawater application bolts. They offer unmatched reliability, longevity, and security, essential for any project that must withstand the harsh conditions of seawater environments.
