Alloy 602CA is a high-temperature alloy that is resistant to metal dusting. Nicrofer 6025 HT, 602CA is a high-carbon, nickel-chromium-iron alloy with micro-alloying elements of titanium, zirconium, aluminum and yttrium. With an operating temperature of up to 1150⁰C (2102⁰F), 602CA has shown exceptional resistance to oxidation at high temperatures.

Common Trade Names: 602 CA, Alloy 602 CA, Nicrofer 6025 HT

Alloy 602 CA is a high-carbon nickel-chromium-iron alloy with additions of the micro-alloying elements titanium and zirconium together with aluminum and yttrium. It is normally supplied in the solution-annealed condition with an oxidized or descaled surface.

This alloy is characterized by excellent high-temperature creep properties; and Exceptional resistance to oxidation at higher temperatures, even under cyclic conditions.  It also possesses very good high-temperature corrosion resistance up carburizing and oxidizing/chlorinating media as well as under metal dusting conditions.

Available Product Forms:
Plate, Sheet, round bar, fittings and ferrules.
