Inconel 825 is a nickel-iron-chromium alloy with added molybdenum, copper, and titanium. The chemical composition of this nickel steel alloy is designed to provide excellent resistance to many corrosive environments. It is similar to Alloy 800 but has improved resistance to water corrosion. It has excellent resistance to reducing and oxidizing acids, stress corrosion cracking, and localized attacks such as pitting and crevice corrosion.

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.
