At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel Coils are crafted to provide exceptional strength, corrosion resistance, and durability for a wide range of industrial applications. Featuring a balanced austenitic-ferritic microstructure, these coils resist pitting, crevice corrosion, and stress-corrosion cracking in chloride-rich and chemically aggressive environments. Manufactured with precision for consistent thickness, dimensional stability, and mechanical reliability, Duplex Steel Coils are ideal for fabrication, forming, and structural applications. Perfect for chemical processing, petrochemical, oil and gas, power generation, and marine industries, they deliver robust, long-lasting, and high-performance solutions in critical industrial operations.
Duplex Steel Coils are composed primarily of chromium, nickel, molybdenum, and nitrogen, forming a balanced austenitic-ferritic microstructure. This composition provides high tensile and yield strength, excellent toughness, and superior resistance to pitting, crevice corrosion, and stress-corrosion cracking. The coils maintain mechanical integrity, dimensional stability, and performance under thermal cycling, high-pressure, and mechanically demanding conditions. Combining corrosion resistance, durability, and high strength, Duplex Steel Coils ensure long-lasting, reliable performance in chemical, petrochemical, offshore, marine, and power generation applications where conventional stainless steels may fail.

Duplex Steel Coils are widely used in industries that require high-strength, corrosion-resistant, and durable metal for fabrication and structural purposes. They are essential in chemical and petrochemical plants for heat exchangers, pressure vessels, storage tanks, and piping components exposed to acids, chlorides, and oxidizing chemicals. Oil and gas industries utilize these coils in offshore platforms, subsea structures, and high-pressure systems. Power generation facilities employ Duplex Steel Coils in turbines, boilers, and cooling water systems. Marine and desalination plants rely on them for seawater-resistant fabrication. The coils provide structural integrity, long-term durability, and reliable performance in harsh, high-pressure, and corrosive industrial environments.
