UNS S32750 Plates & Duplex Steel S32205 Sheet & Plates Supplier in India

Taashvi Special Alloys is a leading UNS S32750 Plates & Duplex Steel S32205 Sheet & Plates Supplier in India, offering durable, high-strength solutions for industries that demand corrosion resistance and mechanical reliability. With our extensive inventory and commitment to quality, we known as a trusted source for duplex stainless steel plates across India.

What is Duplex Stainless Steel?

Duplex stainless steels are a family of stainless alloys known for their dual-phase microstructure consisting of both austenitic and ferritic grains. This combination results in superior strength, excellent corrosion resistance, and high stress tolerance.

Key properties of duplex stainless steel:

  • Higher yield strength compared to austenitic steels
  • Excellent resistance to pitting, crevice, and stress corrosion cracking
  • Lower nickel and molybdenum content, making it more cost-effective

Overview of UNS S32750 Plates

UNS S32750, also known as Super Duplex 2507, is a super duplex stainless steel with high chromium (25%), molybdenum (4%), and nitrogen content. It is ideal for demanding environments, such as offshore, marine, and chemical processing applications.

Key Features:

  • High tensile and yield strength
  • Excellent resistance to chloride stress corrosion cracking
  • Good weldability and formability
  • Excellent performance in seawater and aggressive chemicals

At Taashvi Special Alloys, we supply UNS S32750 plates that meet international standards and are available in various sizes and custom finishes.

Overview of Duplex Steel S32205 Sheet & Plates

UNS S32205, commercially known as Duplex 2205, is a widely used duplex stainless steel grade offering a balanced mix of corrosion resistance and mechanical strength. It contains around 22% chromium, 3% molybdenum, and 5-6% nickel.

Key Features:

  • Twice the strength of standard austenitic stainless steels
  • Excellent resistance to oxidation and corrosion
  • Widely used in chemical tanks, structural piping, and pressure vessels
  • Cost-efficient and versatile

Taashvi Special Alloys stocks Duplex Steel S32205 sheet & plates in multiple dimensions, surface finishes, and thicknesses to meet industry-specific demands.
