High PerformanceNickel Based Corrosion Resistant Alloy October October 2011 2011 HPAlloy C-276 Excellent Resistance to Corrosion Alloy C-276 is a nickel-molybdenumchromium Product High Performance wrought alloy that is generally considered a versatile Alloys can make hot Description corrosion-resistant alloy. Alloy C-276 is an improved rolled, cold worked, & wrought version of alloy C in that it usually doesn't need to be solution heat-treated after welding and has strain hardened high vastly improved fabricability. This alloy resists the formation of grainboundary performance stainless precipitates in the weld heat-affected zone, thus making it suitable for most steel bars inhouse chemical process applications in the as-welded condition. now.
