Incoloy 800H has excellent stress corrosion resistance in water containing chloride and low concentration NAOH. It is widely used in manufacturing stress corrosion-resistant equipment, replacing 18-8 austenitic steel, and is used in pressure water reactor evaporators in the power industry. , high-temperature gas-cooled reactor, sodium-cooled fast reactor heat exchanger, and superheated steam pipe. In the chemical industry, it is used in HNO3 coolers, acetic anhydride cracking tubes, and various heat exchange equipment.
The corrosion resistance of Incoloy is generally superior to that of nickel-copper. It is more resistant to corrosion from reducing media than pure nickel and is more resistant to corrosion from oxidizing media than pure copper. Incoloy 800H Pipe can be used to make nitric acid condensers - resistant to nitric acid corrosion
Incoloy 800H Pipe has good mechanical properties and can be used to make steam heating pipes or heating element pipes.
Incoloy 800H Pipe is suitable for applications in environments up to 500°C. The alloy is supplied in the annealed state.
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.
