Abstract

This specification covers hot- and cold-worked precipitation hardenable cobalt-containing alloys (UNS R30155 and UNS R30816) rod, bar, forgings, and forging stock for high temperature service. The material shall conform to the required chemical composition for carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, columbium, tantalum, iron, cobalt, and nitrogen. The materials shall conform to the required tensile and hardness properties such namely tensile strength, yield strength, alongation and Brinell hardness. The alloys shall also conform to the required stress-rupture properties. Dimensions such as diameter, thickness, or width, out-of-round, corners, cut lengths, straightness for cold-worked and hot-worked rod and bar shall be measured.

Scope

1.1 This specification covers hot- and cold-worked precipitation hardenable cobalt-containing alloys (UNS R30155 and UNS R30816) rod, bar, forgings, and forging stock for high-temperature service.

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.

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.
