Inconel690 alloy tube is mainly a new generation heat transfer tube material for pressurized water reactor steam generators. Its nickel-based alloy contains 27.0~31.0% chromium and approximately 59% nickel. The nickel-based alloy has excellent anti-crystallization properties. Intergranular corrosion and resistance to intergranular stress corrosion cracking.

Inconel 690 Alloy Pipeis mainly used as heat transfer tube material for steam generators in pressurized water reactor power plants and is a technology for steam generators. At present, among the pressurized water reactor power plant units in operation in my country, only Qinshan Phase I uses 800 alloy. Qinshan Phase II, Daya Bay and Ling'ao nuclear power plants all use 690 alloy as the steam generator heat transfer tube material.
1. Marine industry: Monel alloy bars are resistant to saltwater corrosion and are therefore commonly used in marine applications.
2. Chemical processing: Monel alloy bars are used in the chemical industry for heat exchangers, valves, pumps, and other equipment that come into contact with corrosive chemicals.
3. Aerospace industry:
Monel bars are used in aircraft components, especially where corrosion resistance is critical.
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.
