LORK is an excellent high super alloy manufacturer in China.A nickel-chromium-iron alloy with additions of molybdenum and copper. It has good weldability and resistance to intergranular corrosion in the welded condition. The low carbon content helps prevent sensitization and consequent intergranular corrosion of weld heat-affected zones. Used for flue-gas scrubbers and for handling phosphoric and sulfuric acids.
Hastelloy G3 alloy has high tungsten and molybdenum contents, which makes it resistant to corrosion.
The following section will discuss in detail about Hastelloy G3 alloy.

Fabrication and Heat Treatment
Machinability |
Hastelloy G3 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. |
Forming |
Hastelloy G3 alloy can be formed through conventional forming methods. |
Welding |
Welding of Hastelloy G3 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. |
Cold working |
Hastelloy G3 alloy can be cold worked using standard tooling methods. As plain carbon steels produce galling, they are not preferred for forming Hastelloy G3 alloy. Galling can be minimized with the help of heavy duty lubricants. |
Annealing |
Annealing of Hastelloy G3 alloy can be performed at 1177ºC (2150ºF) followed by rapid cooling of air and water quenching. |
Hardening |
Hastelloy G3 alloy can be hardened by cold working. |
Applications |
Hastelloy G3 alloy finds its application in the manufacture of process equipment for mixed acids, sulfate compounds and flue gas scrubbers. |
