(Specification)Standard Specification for Precipitation-Hardening Nickel Alloy (UNS N07718) Plate, Sheet, and Strip for High-Temperature Service
Standard Specification for Precipitation-Hardening Nickel Alloy (UNS N07718) Plate, Sheet, and Strip for High-Temperature Service
ABSTRACT
This specification covers rolled precipitation hardening nickel alloy (UNS N07718) plate, sheet, and strip in the annealed condition (temper) for high-temperature service. The material shall conform to the chemical requirements for carbon, manganese, silicon, phosphorus, sulfur, chromium, cobalt, molybdenum, columbium, niobium, tantalum, titanium, aluminum, iron, copper, nickel, and boron. The material after precipitation hardening shall conform to the mechanical property requirements for tensile strength, yield strength, and elongation. Stress-rupture test shall be performed in accordance to referenced ASTM documents itemized herein.
SCOPE
1.1 This specification covers rolled precipitation hardenable nickel alloy (N07718)* plate, sheet, and strip in the annealed condition (temper).
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 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.
