Product
Characteristics
| 1.According to the preparation process can be divided into
deformation superalloys,
casting superalloys and powder metallurgy superalloys.
2.According to the strengthening mode, there are solid solution
strengthening type, precipitation
strengthening type, oxide dispersion strengthening type and fiber
strengthening type, etc.. |
Standard | GB,AISI,ASTM,DIN,EN,SUS,UNS etc |
Inspection | ISO,SGS,BV and so on. |
Super alloys have the ability to function at very high temperatures
and mechanical stress, and also where high surface stability is
required. They have good creep and oxidation resistance, and can be
produced in a variety of shapes. They can be strengthened by
solid-solution hardening, work hardening, and precipitation
hardening.
Super alloys consist of a number of elements in a variety of
combinations to achieve the desired result. They are further
classified into three groups such as cobalt-based, nickel-based,
and iron-based alloys.
