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.
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:
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:
At Taashvi Special Alloys, we supply UNS S32750 plates that meet international standards and are available in various sizes and custom finishes.
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:
Taashvi Special Alloys stocks Duplex Steel S32205 sheet & plates in multiple dimensions, surface finishes, and thicknesses to meet industry-specific demands.
