Material Notes:

AL 276 alloy is a nickel-chromium-iron-tungsten alloy which is among the most corrosion resistant of alloys currently available. The AL 276 alloy is widely used in the severest environments encountered in the chemical and petrochemical processing, flue gas desulfurization, pulp and paper and other specialized fields. Design of the alloy allows a high level of corrosion resistance to be retained even in the welded condition.This alloy also has good high temperature strength and moderate oxidation resistance although the alloy will eventually form embrittling high temperature precipitates. It has been available for several years and has been used in ASME Boiler and Pressure Vessel related construction. The alloy is readily fabricated by welding using techniques similar to those used for austenitic stainless steels and other nickel base alloys. Precautions are advisable during fabrication because raising the low carbon and silicon contents of the material may adversely affect important properties.Information provided by Allegheny Ludlum
