Incoloy 800Hhas 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 ofIncoloyis 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. It has very good corrosion resistance to sulfuric acid, phosphoric acid, and carbon.Incoloyalloy has excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid, and their derivatives. At the same time, it is more corrosion-resistant than copper-based alloys in seawater.
Incoloyalso has very good corrosion resistance in moderately concentrated alkaline and salt solutions.
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.
