Palgotta Metal Pvt Ltd offers the highest quality Duplex Steel Sheets with superior corrosion resistance, high strength, and hardness. Our sheets are made from a combination of austenitic and ferritic steels, which gives them exceptional mechanical properties.
With our Duplex Steel Sheets, you can experience enhanced resistance to stress, corrosion cracking, crevice corrosion, pitting, and erosion. Duplex sheets have a higher resistance to intergranular corrosion and mechanical properties of both austenitic and ferritic grades. They are also highly resistant to chloride-ion stress-corrosion cracking.
Table of Content
Duplex steel sheets are a type of stainless steel that offers improved strength and corrosion resistance compared to standard austenitic stainless steel. Duplex steel sheets are composed of two different microstructures, ferrite, and austenite, which provide the material with high mechanical properties and make it ideal for use in many industrial applications.
This combination makes duplex stainless steel extremely resistant to a wide range of corrosive environments, such as chloride-containing media, seawater, mild acids, organic acids, and chlorides. Additionally, duplex stainless steels have higher yield strengths than conventional austenitic alloys, making them suitable for elevated temperature service.
What are the features of a Duplex Steel Sheet?
- High strength
- High corrosion resistance
- High-temperature resistance
- High toughness
- Good weldability
- Excellent mechanical properties
What are the advantages of Duplex Steel Sheets?
- Corrosion resistance twice that of traditional austenitic stainless steels
- Superior stress corrosion cracking and pitting resistance compared to austenitic
stainless steel
- Higher strength levels than regular austenitic grades, making it suitable for
heavy load applications.
What are the applications of Duplex Steel Sheets?
Duplex steel sheets have a wide range of applications in the industrial, construction, oil, and gas sectors. The high strength and corrosion-resistant nature make them ideal for use in structural components such as piping systems, heat exchangers, pressure vessels, and tanks. They are also widely used in the marine and offshore industries for applications such as shipbuilding, platform fabrication, and subsea pipelines.
Due to their excellent mechanical properties, duplex stainless steel sheets are also suitable for use in a variety of other industrial applications such as bridge construction, mining equipment, chemical processing equipment, and food processing machinery.
