Products Description
HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.
Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.
Application
1.Digesters and bleach plants in the paper industry.
2.Components exposed to sour gas.
3.Equipment for flue-gas desulfurisation plants.
4.Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments.
5.Sulfuric acid reactors.
6.Organic chloride process equipment.
7.Equipment for processes utilizing halide or acid catalysts.
