Overview


Alloy 276 (UNS N10276)  is a nickel-chromium-molybdenum alloy that has high corrosion resistance in many chemical environments. . It is one of the alloys with the strongest corrosion resistance and one of the materials with the most extensive corrosion resistance.


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.


HASTELLOY C-276 alloy is available in the form of plates, sheets, strips, billets, bars,wires, pipes, tubes, and covered electrodes.  Its applicable fields include Industries such as petrochemical processing, waste gas desulfurization, pulp and paper industry, industrial waste and air pollution control.

Corrosion Resistance


Alloy C-276 can be used in many chemical processes with both oxidizing as well as reducing media. The high chrome and molybdenum concentrations make the alloy resistant to chloride ion attacks. The tungsten content further increases this resistance. VDM® Alloy C-276 is one of the few materials that are resistant against chlorine gas, hypochlorite and chlorine dioxide solutions. The alloy is characterized by excellent resistance against concentrated solutions of oxidizing salts (such as iron III and copper chloride).



Heat Treatment


Solution annealing should take place at temperatures of between 1,100 and 1,160 °C (2,012 and 2,120 °F). The retention

time during annealing depends on the semi-finished product thickness and can be calculated as follows:

· For thicknesses d < 10 mm (0.4 in), the retention time is t = d ∙ 3 min/mm

· For thicknesses d = 10 to 20 mm (0.4-0.8 in), the retention time is t = 30 min + (d – 10 mm) ∙ 2 min/mm

· For thicknesses of d = 20 mm (0.8 in), the retention time is t = 50 min + (d – 20 mm) ∙ 1 min/mm
