Special Alloys
What are Special Alloys?
Special Alloys are high-performance metal alloys engineered to deliver superior resistance to corrosion, high temperatures, pressure, and wear in extreme environments. These alloys include Nickel Alloys, Inconel, Hastelloy, Monel, Titanium, Duplex and Super Duplex Stainless Steel, and Copper Alloys. Their unique mechanical and chemical properties make them indispensable across aerospace, marine, chemical processing, and energy sectors.
Asiad Steel Industries is a trusted supplier of Special Alloys in various forms including bars, sheets, pipes, tubes, fittings, and flanges — tailored to meet critical industrial applications with global quality compliance.
