ASTM B443-00e1

Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy (UNS N06625) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219)* Plate, Sheet, and Strip

SCOPE
1.1 This specification covers rolled nickel-chromium-molybdenum-columbium alloy (UNS N06625) and nickel-chromium-molybdenum-silicon alloy (UNS N06219)* plate, sheet, and strip.
1.1.1 Alloy UNS N06625 products are furnished in two grades of different heat-treated conditions:
Grade 1 (Annealed)--Material is normally employed in service temperatures up to 1100oF (593oC).Grade 2(Solution Annealed)--Material is normally employed in service temperatures above 1100oF (593oC) when resistance to creep and rupture is required.
Note 1--Hot-working or reannealing may change properties significantly, depending on working history and temperatures.
1.1.2 Alloy UNS N06219 is supplied in solution annealed condition only.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
