Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy (UNS N06625) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219)* Plate, Sheet, and Strip
ABSTRACT
This specification covers rolled nickel-chromium-molybdenum-columbium alloy (UNS No. N06625) and nickel-chromium-molybdenum-silicon alloy (UNS No. N06219) plates, sheets, and strips. N06625 alloys shall be furnished in two grades of different heat treatment conditions, namely: Grade 1 (annealed); and Grade 2 (solution annealed). N06219 alloys, on the other hand, shall be furnished in solution annealed condition only. Materials shall be sampled prepared, and tested accordingly to examine their conformance to dimensional (thickness, weight, width, diameter, length, straightness, edges, squareness, and flatness), mechanical (tensile and yield strengths, and elongation), and chemical composition requirements.
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 1100F (593C).Grade 2 (Solution Annealed)
Material is normally employed in service temperatures above 1100F (593C) 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.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
