Model: Hastelloy G-30 UNS N06030 DIN W. Nr. 2.4603 Alloy 20 N08020 NS143 Carpenter20Cb3 AISI Alloy20Cb-3 ASTM Alloy20Cb-3
Code: Super Alloy-Sheet-14

Super alloys or high performance alloys are used in environments with very high temperature above 540ºC (1000ºF) where deformation resistance and high surface stability are chiefly required. They have good oxidation and creep resistance. Cobalt-base, nickel-base and iron-base alloys are the three major types of super alloys. The iron-base super alloys are generally wrought alloys provided with stainless steel technology. Nickel-base and cobalt-base super alloys may be cast or wrought based on its composition or application. Super alloys can be generally forged, rolled to sheet or produced in different shapes. Highly alloyed compositions are formed as castings. They can be strengthened using hardening techniques like work hardening, solid-solution hardening and precipitation hardening.
