Inconel 690 Alloy forging Rods High-Chromium Nickel Alloy Round Bar
Alloy 690, also known as Inconel 690, is a high-chromium nickel alloy. Its main features are as follows:
- Excellent corrosion resistance: Alloy 690 performs well in a variety of corrosive environments, especially in chlorine-containing environments, sodium hydroxide solutions, and highly corrosive media such as sulfuric acid, nitric acid, and hydrochloric acid.
- Good high-temperature properties: The alloy has excellent oxidation resistance and creep resistance and is suitable for high-temperature and high-pressure environments.
- Mechanical properties: At room temperature, Alloy 690 has high tensile strength and good ductility and toughness.
- Processing and welding properties: It can be processed by hot processing, cold processing and welding.
