All stainless tubes that contain more than 30% of nickel are referred to as nickel alloys.
Nickel alloys is a firm metal of silver-white colour. It is not oxidized and has a brilliant polish. Nickel is a material which serves as the active catalyst at many chemical processes. Nickel alloys are used for high-temperature and highly corrosive media. Such conditions are typical for power generation industry, chemicalpetrochemical industry, aerospace engineering. Advanced nickel-based high strength alloys traditionally have nickel and chromium as their foundation, with elements such as molybdenum, tungsten and cobalt added to confer additional solid solution strengthening. Where high temperature strength is critical, additions of aluminum, titanium and niobium, resulting in precipitation hardening, must be added.
Nickel-based alloys include Alloy 600 (UNS 06600), Alloy 800 (UNS N08800), Alloy 825 (UNS N08825), Alloy 625 (UNS N06625), etc.
Nickel alloys provide better solutions and improved technological standards for stainless steel tubes manufacturing.
