GENERAL PROPERTIES
Super alloys are metallic alloys used at high temperatures above 540°C (1000°F) where high surface stability and deformation resistance are mainly required. Three major classes of super alloys include iron-base, nickel-base and cobalt-base alloys. The iron-base super alloys are generally wrought alloys with stainless steel technology. Nickel-base and cobalt-base super alloys may be cast or wrought based on its composition or application. Super alloys are commonly forged, rolled to sheet or produced in various shapes. However, highly alloyed compositions are produced as castings.
The following datasheet provides a detailed description of Alloy G, which has good resistance to both oxidation and reduction.
MACHINEABILITY
Alloy G 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.

WELDING
Welding of Alloy G 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.
HEAT TREATMENT
Annealing of Alloy G can be performed at 1177°C (2150°F) followed by rapid cooling of air and water quenching.
