Hastelloy C276 Tube

UNS N10276

Shanghai Yikai Metal Products Co., Ltd can supply hastelloy c276 tube according to customers' requirement. These tubes are with inherent resistance to corrosion and high strength. These tubes are perfect for use in marine applications and harsh industrial environments.

Hastelloy C276 alloy is a nickel-molybdenum-chromium wrought alloy that is generally considered a versatile corrosion-resistance alloy. C-276 alloy is an improved wrought version of alloy C in that it usually doesn't need to be solution heat-treated after welding and has vastly improved fabricability. This alloy resists the formation of grain-boundary precipitaties in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition. However, in environments where attack of the C-276 alloy weld joint is experienced, C-22 weld filler materials should be considered.

Hastelloy C-276 Corrosion resistance

C276 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make it corrosion resistance better.C276 is one of a few material that can resist the corrosion of most chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).
