Superalloys resist creep and oxidation. They are also called high performance alloys and can be shaped. Super alloys are strengthened by work hardening, precipitation hardening, and solid-solution hardening. Apex Metal India is a significant supplier and stockiest of nickel in all grades.


These alloys can withstand high temperatures, mechanical stress, and require high surface stability. Nickel-chromium alloy Inconel 690™M Due to its high chromium content, it is resistant to hot gases and oxidising chemicals. The datasheet below describes Inconel 690™.
