Nomonic 80A (GH80A) is a high-temperature alloy based on nickel-chromium, with aluminum and titanium added to form r-phase dispersion strengthening. Except for the slightly higher aluminum content, it is similar to GH4033. The service temperature is 700~800℃, and the temperature is 650~850℃. It has good creep properties and anti-oxidation properties.

GH80A alloyhas good hot and cold processing properties and mainly supplies hot-rolled bars, cold-drawn bars, hot-rolled plates, cold-rolled plates, strips and rings, etc. It is widely used in the manufacture of engine rotor blades, guide blade supports, bolts, blade lock plates, and other parts.
GH80A alloy plates are mainly used to manufacture engine rotor blades, guide blade supports, sector mounting rings, bolts, blade lock plates, and other parts.
GH80A alloymainly includes hot-rolled bars for blades with a diameter of d20~55mm, and hot-rolled or forged bars with a diameter of no more than 300mm;
Cold-drawn bars: round bars with a diameter of 8 to 45mm and hexagonal bars with an inscribed circle diameter of d8 to 36mm; rolled shaped parts with an outer diameter of 1000mm, an inner diameter of 900mm, and a height of 130mm; hot-rolled plates with a thickness not greater than 9.5, thickness Cold-rolled thin plates not larger than 4.0, cold-rolled strips with a thickness not larger than 0.8mm.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
