Corrosion Material’s C276 is a solid-solution-strengthened, nickel-molybdenum-chromium alloy with a small amount of tungsten, which exhibits excellent corrosion resistance in an assortment of harsh environments. Applications include and are not limited to, stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, heat exchangers, reaction vessels and evaporators. Industries where C276 can be utilized are petrochemical and chemical processing, power generation, pharmaceutical, pulp and paper production and waste treatment to name a few.

C276 is known as the most universally corrosion resistant material available today. It is used in a variety of environments from moderately oxidizing
to strong reducing conditions. The limiting factor when dealing with strong oxidizing environments is the low Cr content, which means that hot,
concentrated nitric acid environments are NOT desirable. Although, C276 has exceptional resistance to sulfuric acid and hydrochloric acid, acid chlorides, solvents, formic and acetic acids, acetic anhydride, wet chloride gas, hypochlorites and chlorine solutions. Also, it has excellent resistance to phosphoric acid at all temperatures below boiling and at concentrations lower than 65%.Alloy C276 has excellent resistance to pitting, stress-corrosion cracking and to oxidizing atmospheres. C276 also exhibits excellent resistance to corrosion by seawater especially under crevice conditions, which induce attack in other commonly used materials.

Alloy C276 can be readily welded by most standard processes including GTAW (TIG), PLASMA, GMAW (MIG/MAG) and SMAW (MMA).

A post weld heat treatment is not necessary
