ASTM B444 specification covers UNS N06625 and UNS N06852 nickel-chromium-molybdenum-columbium alloys and UNS N06219 nickel-chromium-molybdenum-silicon
alloy in the form of cold-worked seamless pipe and tube. UNS N06625 products are furnished in annealed Grade 1 and solution annealed Grade 2 while UNS N06219 and
UNS N06852 are in solution annealed condition only. Chemical testing shall be performed on each type of material and shall conform to the chemical composition limits
specified for carbon, manganese, silicon, phosphorus, sulfur, chromium, tantalum, columbium, cobalt, molybdenum, iron, aluminum, titanium, copper, and nickel.
The material shall undergo tensile testing and shall conform to the required room temperature tensile properties like tensile strength, yield strength,
and elongation depending on the heat treatment used and including small diameter and light-walled tubing. Each pipe or tube shall undergo hydrostatic
testing and shall conform to the allowable fiber stress and also be examined with a nondestructive electric test as prescribed.
