ASTM B444 Tubing, ASTM B444 Tube, ASTM B444 Pipe Supplier
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. ASTM B444 Grade 1 (annealed) Material is normally employed in service temperatures
up to 1100°F (593°C). ASTM B444 Grade 2 (solution annealed) Material is normally employed in service temperatures above 1100°F (593°C) when resistance to creep and rupture is required. ASTM B444 UNS N06219 and ASTM B444 UNS
N06852 are supplied in the solution annealed condition only.
