Duplex stainless steel is a type of steel that is characterized by its high strength and corrosion resistance. It is called a "duplex" because it contains approximately equal proportions of two phases, austenitic and ferritic. The specific composition of duplex steel plates can vary depending on the specific grade of duplex steel being used. Palgotta Metal Pvt Ltd is a leader in the production of Duplex Steel Plates. Our plates are made from high-grade stainless steel and feature excellent wear & tear properties and superior tensile strength.

What are Duplex Steel Plates?
Duplex steel plates are made from an alloy of ferrous and non-ferrous metals, which combine the characteristics of both materials. This makes them especially strong and resistant to corrosion. They are often used in industries where high strength, corrosion resistance, and temperature resistance are needed, such as marine applications, chemical processing plants, oil refineries, power generation plants, etc.
What are the features of Duplex Steel Plates?
The main features of duplex stainless steel plates include the following:
• Superior strength-to-weight ratio compared to other steels.
• Excellent pitting and crevice corrosion resistance.
• Improved oxidation resistance.
• Good cryogenic toughness.
• Good weldability and machinability.
• Good formability.
• Higher yield strength than austenitic stainless steels.
• Good thermal conductivity.
What are the advantages of Duplex Steel Plates?
The advantages of duplex steel plates include the following:
• Increased life expectancy.
• Improved resistance to stress corrosion cracking and general corrosion.
• Elevated strength-to-weight ratio.
• The reduced weight of components.
• Lower cost than other metals such as titanium or nickel alloys.
• Enhanced weldability.
What are the applications of Duplex Steel Plates?
Duplex steel plates are used in various industries, including marine, chemical, food, pulp, paper processing, oil refining, power generation plants, and nuclear reactors. They can also fabricate industrial equipment and structural members for bridges, buildings, petrochemical tanks, pressure vessels, off-shore drilling platforms, and more. Additionally, they are often used for making pipelines in the oil & gas industry due to their superior corrosion resistance.
The duplex plate is excellent for various industrial applications requiring strength and corrosion resistance. Their mechanical properties and cost-effectiveness make them a viable option for many industries.
