602 CA®

(English)  

602 CA® from NeoNickel is one of the most popular of the speciality metals that we have supplied to customers in a wide variety of industries for many years for one good reason…it is the most oxidation resistant and high strength Nickel alloy available.  This is down to its unique composition, which has high chromium content as well as additions of aluminium and yttrium, which allow the alloy to develop a tightly adhering oxide scale.

Properties

(English) The main features of 602 CA® are as follows:

  • Outstanding resistance to cyclic oxidation through 1232°C 
  • Excellent high temperature creep strength
  • Resistant to carburizing and nitriding environments
  • Highly resistant to grain growth in service
  • Superior behaviour in oxidizing/chloridizing environments
  • Good resistance to metal dusting

Carburisation

(English) 602 CA® possess high nickel content and as a result it provides outstanding resistance to carburisation attack.

Fabrication

(English) For joints less than 3/16 inch thick, 100% argon is acceptable for a shielding gas. For heavier joints it is recommended to use AR Ni5He5CD300 gas from AirGas which was designed to reduce the likelihood of weld solidification cracks. For GTAW welding the use of 98% Argon, 2% Nitrogen for the shielding gas is suggested to minimize the likelihood of weld solidification cracking.

Oxidation

(English) 602 CA® is one of the most oxidation resistant nickel alloys available. Chromium (25%) supplemented with aluminum (2.2%) and a micro-alloying addition (0.1%) yttrium form a very thin protective oxide scale. The aluminum addition allows for the formation of a continuous homogenous self repairing AI2O3 subscale. The addition of yttrium improves the adhesion and spalling resistance of the chromium and aluminum oxide scales. The extremely low scaling rate of 602 CA® makes it an excellent candidate for applications such as high purity alumina calciners, where minimal contamination from scaling is permissible. 602 CA® is one of the most oxidation resistant nickel alloys available.
