What is equivalent to Hastelloy c4?
introduce
Superalloys or high-performance alloys have good creep and oxidation resistance. They can be used at very high temperatures, can withstand extreme mechanical stress, and can be used wherever high surface stability is required. They can be made into various shapes. Alloys are divided into three categories: nickel-based alloys, iron-based alloys and cobalt-based alloys. Cobalt-based superalloys have higher melting points than nickel- or iron-based alloys.
