Hastelloy C276 alloy has good high temperature resistance. It can maintain its mechanical properties and chemical stability under high temperature conditions, especially suitable for high temperature oxidation environments.
The high temperature resistance of Hastelloy C276 is mainly due to its unique chemical composition and microstructure. The main ingredients in the alloy include nickel, chromium and molybdenum, which improve the oxidation resistance and high temperature resistance of Hastelloy C276 alloy.
Chemical composition and high temperature resistance
The main chemical components of Hastelloy C276 include nickel (about 65%), chromium (about 15%), molybdenum (about 4.5%), iron (about 6%) and other elements such as tungsten, cobalt, etc. At high temperatures, a dense oxide film can be formed to effectively prevent further penetration of oxygen, thereby reducing the oxidation loss of the base metal and maintaining the strength and toughness of the alloy.
specific temperature range
Hastelloy C276 alloy is typically used continuously at temperatures below about 650°C (1200°F) because it maintains good strength and corrosion resistance in this temperature range.
However, it also has a certain short-term endurance at higher temperatures and can withstand higher temperatures in a short period of time without significant performance degradation.
GNEE implements strict whole-process control for Hastelloy C276 alloy pipes. Ensuring that product quality meets user requirements is the purpose of Jiuli's service to users. The company combines special inspection, mutual inspection, and random inspection (patrol inspection) to ensure that the quality of products is always under control during the production process, including radiographic inspection, ultrasonic inspection, eddy current inspection, water pressure test, and 100% PMI inspection.
