Hastelloy C276 Tube

ASTM B622 UNS N10276 Seamless Tube and Nickel Alloy C276 Tubing manufacturer in Mumbai

Hastelloy C276 Tube is a nickel-molybdenum-chromium super alloy with an addition of tungsten which is designed to have excellent corrosion resistance in a severe wide range of environments. 

Hastelloy C276 Tubing has high nickel and molybdenum contents make it resistant to pitting and crevice corrosion in reducing environments while chromium delivers oxidizing resistance to media. 
During welding Hastelloy C276 Seamless Tube low carbon content minimizes carbide precipitation in order to maintain corrosion resistance in as-welded structures.
In the weld heat-affected zone Alloy C276 Tubing is resistant to the formation of grain boundary precipitates, thus which makes it appropriate for most chemical processing application in an as welded condition.

Hastelloy C276 Welded Tubing is one of the most adaptable corrosion resistant alloys. It exhibits excellent resistance in a wide variety of chemical process environments including those with hot contaminated organic and inorganic media, formic and acetic acids, brine and hypochlorite, ferric and cupric chlorides, chlorine, acetic anhydride, seawater, and chlorine dioxide solutions

Alloy C276 Tube resists formation of grain boundary precipitates in the weld heat affected zone which makes it useful for most chemical processes in the as-welded condition. 

ASTM B622 UNS N10276 Tube can be hot-upset, forged and impact extruded. Although it tends to work-harden, you can have it successfully deep-drawn, spun, punch or press formed. It can be welded by using all common methods of welding.

2.4819 Alloy C276 Tube are useful for flue-gas desulfurisation plants equipment, Equipment for processes utilizing halide or acid catalysts, components exposed to sour gas, digesters and bleach plants in the paper industry, Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments
