This specification covers hot- and cold-finished bars and shapes of wrought nickel-iron-chromium-silicon alloys with UNS Nos. N08330 and N08332 intended for heat-resisting applications and general corrosive service. Materials shall be furnished in the heat-treated condition, except that cold-drawn hexagons may be given a cold-drawn sizing pass subsequent to the final heat treatment. Specimens shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, width, length, and angularity), mechanical (tensile and yield strengths, and elongation), chemical composition, and grain size requirements.

1.1 This specification2 covers wrought alloys UNS N08330 and UNS N08332 in the form of hot-finished and cold-finished bar and shapes intended for heat-resisting applications and general corrosive service.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 Safety Data Sheet (SDS) 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.
