ASTM B637-06e1

Standard Specification for Precipitation-Hardening Nickel Alloy Bars, Forgings, and Forging Stock for High-Temperature Service

ABSTRACT
This specification covers hot- and cold-worked precipitation-hardenable nickel alloy rod, bar, forgings, and forging stock for high-temperature service. Chemical analysis shall be performed on the alloy and shall conform to the chemical composition requirement in carbon, manganese, silicon, phosphorus, sulfur, chromium, cobalt, molybdenum, columbium, tantalum, titanium, aluminum, zirconium, boron, iron, copper, and nickel. The material shall follow recommended annealing treatment, solution treatment, stabilizing treatment, and precipitation hardening treatment. Tension testing, hardness testing and stress-rupture testing shall be performed on the material and shall comply to the required tensile strength, yield strength, elongation, reduction in area, and Brinell hardness.
SCOPE
1.1 This specification covers hot- and cold-worked precipitation-hardenable nickel alloy rod, bar, forgings, and forging stock for high-temperature service (Table 1).
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in brackets are for information only.
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.
