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.
RA 602 CA® alloy is the most oxidation resistant/high strength nickel alloy available. It is capable of extreme temperature use up to 2250°F (1232°C). For thermal processing applications where minimal product contamination is necessary, the oxidation/scaling resistance of RA 602 CA® is extremely desirable. A high chromium content, along with aluminum and yttrium additions, allows the alloy to develop a tightly adhering oxide scale.
A relatively high carbon content combined with the alloying additions of titanium and zirconium results in high creep rupture strength. RA 602 CA® provides 150% of the strength of other commonly used nickel alloys such as alloy 600.
