Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloy (UNS N06625), Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219), and Nickel-Chromium-Molybdenum-Tungsten Alloy (UNS N06650) Rod and Bar

ABSTRACT
This specification covers nickel-chromium-molybdenum-columbium (UNS N06625), nickel-chromium-molybdenum-silicon alloy (UNS N06219), and nickel-chromium-molybdenum-tungsten alloy (UNS N06650) in the form of hot-worked rod and bar and cold-worked rod. The matreial shall conform to the required chemical composition for carbon, manganese, silicon, phosphorus, sulfur, chromium, columbium, tantalum, cobalt, molybdenum, iorn, aluminum, titanium, copper, nickel, tungsten, and nitrogen. The materials shall conform to the the heat treatment and room temperature tensile properties such as tensile strength, yield strength, and elongation. Dimensions of the alloys such as diameter, thickness, or width, length and straightness shall also be determined.
SCOPE
1.1 This specification covers nickel-chromium-molybdenum-columbium (UNS N06625), nickel-chromium-molybdenum-silicon alloy (UNS N06219), and Nickel-Chromium-Molybdenum-Tungsten Alloy (UNS N06650)2 in the form of hot-worked rod and bar and cold-worked rod in the conditions shown in Table 1. (A) Forging quality is furnished to chemical requirements and surface inspection only. No tensile properties are required. Forging stock is typically supplied in the hot worked condition, (see X1.1.5).(B) Annealed 1600°F (871°C) minimum.(C) Solution annealed at 2000°F (1093°C) minimum, with or without subsequent stabilization anneal at 1800°F (982°C) minimum to increase resistance to sensitization.  
† MPa was corrected editorially.  
1.1.1 UNS N06625 products are furnished in two grades of different heat-treated conditions:
1.1.1.1 Grade 1 (Annealed)—Material is normally employed in service temperatures up to 1100°F (593°C).
1.1.1.2 Grade 2 (Solution Annealed)—Material is normally employed in service temperatures above 1100°F (593°C) 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 Alloys UNS N06219 and UNS N06650 are supplied in solution annealed condition only.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 The following precautionary caveat pertains only to the test methods portion, Section 12, of this specification: 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.
