What is Super Duplex 2507?

Super Duplex 2507 is a high alloy and corrosion-resistant stainless steel known for its strength and excellent corrosion resistance properties. It has increased chromium, molybdenum, and nitrogen content, giving it superior pitting resistance to other stainless steels. Its high strength allows for use in applications requiring higher mechanical strengths while providing great corrosion resistance properties.

This includes seawater desalination plants and offshore oil rigs that require a strong material to resist the harsh environment of the ocean. Super Duplex 2507 is also resistant to chloride stress cracking, crevice corrosion, sulfide stress cracking, erosion corrosion and general inorganic acids like nitric acid. It can be used in atmospheric and pressurized systems due to its great performance under various conditions.

Properties of Super Duplex 2507 Bolt

Super Duplex 2507 bolts are made from a stainless steel alloy of 25% chromium, 7% nickel, and other trace elements like molybdenum and nitrogen. This combination gives the alloy excellent corrosion resistance and superior strength to standard austenitic steels. These bolts have a tensile strength ranging from 860MPa to 1400MPa with excellent fatigue and wear resistance properties. Moreover, they offer great dynamic load-bearing capacity due to their high yield strength, twice as much as the national duplex grades. In addition, their exceptional pitting resistance makes them highly durable in harsh environmental conditions for long-term use with minimal maintenance requirements while providing outstanding levels of dimensional accuracy throughout their lifespan.

Applications of Super Duplex 2507 Bolt

Super Duplex 2507 Bolts are a special stainless steel alloy with superior strength and corrosion resistance compared to other bolt materials. These bolts have many practical applications, such as oil & gas industry components, piping systems, heat exchangers, pressure vessels and tanks. They are also used in marine engineering, pulp & paper equipment manufacturing, chemical process engineering projects, etc. In addition to these industrial applications, Super Duplex 2507 Bolts can be used in residential areas due to their extreme durability and ability to resist corrosion even under harsh environmental conditions. These bolts will increase the life span of your infrastructure, making them an ideal choice for any installation.

Advantages of Using Super Duplex 2507 Bolt

The use of Super Duplex 2507 Bolt have numerous advantages, including:

High strength and durability

Corrosion resistance properties

Reduced maintenance costs

Increased lifespan

Resistance to pitting, erosion, and stress-corrosion cracking

Moreover, bolts made of Super Duplex 2507 can withstand extreme temperatures and pressures, making them ideal for use in highly demanding industries.
