Standard Specification for Nickel-Chromium-Silicon Alloy Billets and Bars
ABSTRACT
This specification covers wrought heat-resisting alloy UNS N08330 in the form of billets and bars only for reforging. The material shall undergo chemical and product analysis and conform to the requirements as to chemical composition specified for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, lead, tin, and iron.
SCOPE
1.1 This specification covers wrought heat-resisting alloy UNS N08330 in the form of billets and bars only for reforging.
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, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
