Performing well under high pressure and temperature

602 CA® can be used in a variety of applications, here are just a few examples:

  • Radiant tubes
  • Muffles
  • Furnace retorts

About 602 CA®

602 CA® has a high creep rupture strength, providing up to 150% of the strength of other Nickel Alloys.  Exposure to Carbon rich gases can cause carburisation. Due to its high Nickel content, 602 CA® has an outstanding resistance to carburisation, ensuring prolonged ductility in the face of Carbon Monoxide (CO) and Methane (CH4).

Performing well under high pressure and temperature, 602 CA® is extensively used in thermal processing equipment.

FAQs & Resources

The alloy with the highest temperature oxidation resistance is 602 CA®. This alloy has excellent elevated temperature oxidation resistance up to 1232°C. Above this temperature the only materials which will operate are molybdenum or ceramics.

This is due to its chemistry. High chromium, aluminium and an yttrium addition allows the alloy to develop a tight chromium oxide scale combined with an alumina subscale. The addition of yttrium prevents carbon from being absorbed into the metal.

Alloys such as 602 CA® are usually welded with matching composition fillers, modified by restrictions on Sulphur, Phosphorus, Silicon and Boron. Titanium is added for de-oxidation. The weld consumables improve resistance to hot cracking when they contain Manganese, Carbon, Niobium or Molybdenum.

Outstanding resistance to cyclic oxidation resistance. This combined with outstanding resistance to oxidising / chloridising environments. In addition, the alloy has good carburisation resistance and excellent high temperature creep – rupture strength.
