Hastelloy C22 Hexagon Screws Corrosion Resistant Material

Hastelloy C22 is a special alloy with excellent corrosion resistance and high temperature strength, which is widely used in aerospace, petrochemical and marine engineering. Its composition, performance, processing technology and market prospects have attracted attention, and it has broad prospects for future development.

1. Composition and performance

Hastelloy C22, also known as Hastelloy C-22, is a solid solution strengthened nickel-based alloy. Its main components include nickel, cobalt, chromium, tungsten, molybdenum and other elements, and contain a small amount of alloying elements such as aluminum, titanium and nitrogen. The specific ratio of these elements gives Hastelloy C22 excellent corrosion resistance and high temperature strength.

In terms of corrosion resistance, Hastelloy C22 can resist the erosion of a variety of corrosive media, including wet chlorine, nitric acid, and mixed acids of oxidizing acids containing chloride ions. Its high molybdenum and chromium content makes it resistant to chloride ion erosion, and the addition of tungsten further improves its corrosion resistance. In addition, Hastelloy C22 also has excellent resistance to oxidative water media and can maintain stable performance in a variety of harsh environments.

In terms of high temperature strength, Hastelloy C22 also performs well. Its tensile strength is as high as 860MPa and its elongation reaches 40%, which enables it to maintain sufficient strength and stability in high temperature environments.
