  • Duplex Stainless Steel Manufacturer

Duplex stainless steel is a type of stainless steel that has a two-phase microstructure consisting of both austenitic and ferritic phases in equal proportions. This unique microstructure gives duplex stainless steel excellent mechanical and corrosion-resistant properties.

At Omsteel, we offer a wide range of duplex stainless steel products in various grades, shapes, and sizes to cater to our customers’ diverse needs. Our duplex stainless steel products are highly durable, versatile, and corrosion-resistant, making them ideal for use in harsh environments such as offshore oil rigs, chemical processing plants, and marine applications.

One of the significant benefits of duplex stainless steel is its high strength, which allows it to withstand high-pressure and high-stress environments. Duplex stainless steel also has excellent corrosion resistance properties, making it ideal for use in corrosive environments, including acidic and chloride-containing environments.

Duplex stainless steel is easy to fabricate, weld, and machine, making it an attractive option for a wide range of applications. At Omsteel, we ensure that our duplex stainless steel products are of the highest quality, and our team of experts works tirelessly to meet our customers’ specifications and requirements.

Properties of Duplex Stainless steel

High strength

Duplex steel has higher strength than conventional austenitic stainless steel, which allows it to be used in applications where high strength is required.

Corrosion resistance

Duplex steel has excellent corrosion resistance, especially in harsh environments such as seawater.

Weldability

Duplex steel is generally considered to be highly weldable, although care must be taken to avoid certain welding defects that can occur.

Toughness

Duplex stainless steel has good toughness and ductility, which makes it less prone to cracking and failure.

FAQ

What are the properties of duplex stainless steel?

Duplex stainless steels are highly resistant to corrosion and show excellent resistance to intergranular corrosion. They exhibit exceptional resistance to stress corrosion cracking, even in environments containing chloride and sulphide.

What is the difference between stainless steel and duplex?

Duplex stainless steels are stronger than austenitic stainless steels, with roughly twice the strength. They also have better resistance to certain types of corrosion, such as pitting, crevice corrosion, and stress corrosion cracking. In addition, duplex stainless steels have improved toughness and ductility compared to ferritic stainless steel.

What is the grade of duplex steel?

There are several grades of duplex steel, each with its own unique chemical composition and properties. Some of the most common grades include: Duplex 2205, Duplex 2304, Duplex 2507, Duplex LDX2101. Know more.

What is the price of 1Kg Duplex steel?

Duplex stainless steel is generally more expensive than austenitic stainless steel due to its higher alloy content and more complex manufacturing process. The Cost of Duplex steel if Rs 500*/Kg. Contact us to Know more.
