GH4202 is a Ni-based precipitation hardening deformed high-temperature alloy with a service temperature of -253-800 degrees Celsius. Wu and Mo elements are added to the alloy for solid solution strengthening, aluminum and titanium elements are added to form an aging physical and chemical phase, and a small amount of boron and cerium are added for solid solution strengthening and strengthening. At grain boundaries, the alloy has excellent comprehensive mechanical properties and a stable structure. The alloy has high corrosion resistance and oxidation resistance.

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.
