Alloy X-750
2.4669 / Alloy X-750 is a nickel-chromium-iron alloy.
Inconel Alloy 600 alaşımına benzerdir. Fakat alüminyum ve titanyum ilavesi olduğu için çökelme sertleşmesi ile şertleştirilebilir. 700 °It is similar to Inconel Alloy 600 but can be hardened by precipitation hardening due to the addition of aluminum and titanium. It exhibits high tensile and creep rupture strength even at 700°C, and it also shows excellent oxidation and corrosion resistance
