Basic information:
Chromium-niobium alloy is an important superalloy with the following properties:
High temperature strength: Chromium-niobium alloy has excellent high temperature strength and oxidation resistance, and can maintain stability in high temperature environment.
Corrosion resistance: The alloy has good corrosion resistance and can resist oxidation, vulcanization and carbonization at high temperatures.
Low coefficient of thermal expansion: Chromium-niobium alloy has a low coefficient of thermal expansion, which makes it maintain good dimensional stability at high temperatures.
