ASTM B622 Nickel Alloy C276 Seamless Pipe With Cold Rolled
C276 Pipe/Tube:
C-276 is a nickel-based alloy of nickel-molybdenum-chromium-iron-tungsten and is one of the most corrosion-resistant of modern metal materials. It is mainly resistant to wet chlorine, various oxidizing chlorides, chlorinated salt solutions, sulfuric acid, and oxidizing salts, and has good corrosion resistance in low and medium temperature hydrochloric acid.
Therefore, it has been widely used in harsh corrosive environments, such as chemical, petrochemical, flue gas desulfurization, pulp and paper making, environmental protection, and other industrial fields in the past three decades.
C276 Pipe/Tube Material Grade:
1. Material Grade: UNS N10276, UNS N10001, UNS N10665, UNS N10675, UNS N06022, N08800,N08825, N04400; etc
2. Outer Diameter: 3.18mm-101.6mm
Wall Thickness: 0.5mm-20mm
3. Length: Normally fixed length 6m, can as per customer’s requirement
4. Standard: ASTM B169; ASTM B167; ASTM B444; ASTM B622 etc.

C276 Pipe/Tube Basic Information:
Alloy C276 / UNS N10276 Corrosion resistance:
C276 alloy suits many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist chloride corrosion, and tungsten makes its corrosion resistance better.C276 is one of a few materials that can resist the corrosion of most chlorine, hypochlorite, and chlorine dioxide, this alloy has prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).
