- ALLOY 602CA
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 and carburizing and oxidizing/chlorinating media as well as under metal dusting conditions. Typical applications are:
Radiant tubes, Furnace muffles, Rotary and shaft furnaces, Kiln rollers and other furnace installations ,Glass pot for melting radioactive waste ,Methanol and ammonia synthesis, Hydrogen production, Reformers in the chemical and petrochemical industries, Components in automotive exhaust systems, Glow plugs for diesel engines
