At Radiant Industries, we are committed to delivering advanced stainless steel solutions, and Duplex Stainless Steel stands out as one of our most high-performance product categories. Engineered for strength, durability, and resistance, duplex grades combine the best of both austenitic and ferritic stainless steels.
Duplex stainless steels are characterized by a two-phase microstructure consisting of approximately equal parts austenite and ferrite. This balanced structure imparts superior mechanical strength, excellent corrosion resistance, and enhanced stress corrosion cracking resistance—especially in aggressive environments like chlorides and seawater.
These grades typically contain 22–25% chromium, 4–7% nickel, and molybdenum (up to 3%), giving them a unique advantage over standard stainless steels in critical applications.
Why Choose Duplex from Radiant Industries?
Radiant Industries manufactures high-quality duplex stainless steel bars and wires, tailored for industries that demand exceptional strength and corrosion resistance under tough conditions. Our duplex products undergo stringent quality control and are produced using state-of-the-art facilities designed for precision and performance.
Key Properties
High Strength
Duplex stainless steels offer almost twice the strength of austenitic grades, allowing for reduced material thickness and cost savings in structural applications.
Corrosion Resistance
Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich and acidic environments.
Weldability
Duplex grades have good weldability, with reduced risk of distortion due to their low thermal expansion. However, welding requires controlled heat input and post-weld treatments for optimal performance.
Toughness
These steels maintain good toughness and ductility, even at low temperatures, making them suitable for dynamic and impact-prone applications.
Applications of Duplex Stainless Steel
Thanks to its outstanding strength and corrosion resistance, duplex stainless steel from Radiant Industries is widely used in:
-
Oil & Gas Industry (offshore platforms, pipelines, pressure vessels)
-
Chemical Processing (tanks, heat exchangers, reactors)
-
