    2.4633 / Alloy 602 CA is a high carbon content nickel-chromium-iron-molybdenum alloy with yttrium and aluminum additions.          
It is a high oxidation-resistant and high-strength nickel alloy. It can withstand high temperatures up to 1200C. °When combined with relatively high carbon content and alloy additions of titanium and zirconium, it results in high creep rupture strength.
