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.

HASTELLOY(r) G30(r) alloy can be machined using conventional techniques employed for iron based alloys. The quality of the alloy can be improved with the utilization of water-base coolants. Heavy duty machining tools and equipment can be used prior to cutting in order to reduce chattering or work-hardening of the alloy.

HASTELLOY(r) G30(r) alloy can be formed through conventional forming methods.

Welding of HASTELLOY(r) G30(r) alloy is performed through commonly used welding techniques like gas tungsten arc welding, shielded metal-arc welding, metal-arc welding and submerged-arc welding. However, an alloy filler metal that suits this alloy should be used.

HASTELLOY(r) G30(r) alloy is capable of being annealed. However, this alloy must be solution-annealed after hot forming in order to restore its resistance to corrosion.

As HASTELLOY(r) G30(r) alloy has good ductile property, it can be forged easily.

HASTELLOY(r) G30(r) alloy can be cold worked using standard tooling methods. As plain carbon steels produce galling, they are not preferred for forming HASTELLOY(r) G30(r) alloy. Galling can be minimized with the help of heavy duty lubricants.

HASTELLOY(r) G30(r) alloy can be annealed at 1177oC (2150oF) followed by rapid cooling of air and water quenching.

HASTELLOY(r) G30(r) alloy can be hardened by cold working.

The following are the major applications of HASTELLOY(r) G30(r) alloy:

• Chemical process equipment

• Reheater tubes

• Pump components
