1.1 This specification 2 covers forgings of: Alloy Type UNS Number(s) Fe-Ni-Cr-Mo-N N08367 Low-carbon Cr-Ni-Fe-N R20033 Low-carbon Ni-Cr-Mo N06035, N06058, N06059, N06044 Low-carbon Ni-Cr-Mo-Cu N06200 Low-carbon Ni-Cr-Mo-W N06686 Low-carbon Ni-Fe-Cr-Mo-Cu N08031, N08034 Low-carbon Ni-Mo-Cr N10276, N06022, N10362 Low-carbon Ni-Mo-Cr-Ta N06210 Ni N02200 Ni-Co-Cr-Si N12160 Ni-Cr-Al N06699 Ni-Cr-Co-Mo N06617 Ni-Cr-Fe N06600, N06603, N06690 Ni-Cr-Fe-Al N06025 Ni-Cr-Fe-Si N06045 Ni-Cr-Mo-Nb N06625 Ni-Cr-Mo-Si N06219 Ni-Cr-Mo-W N06110 Ni-Cr-W-Mo N06230 Ni-Cu N04400 Ni-Fe-Cr N08120, N08800, N08810, N08811 Ni-Fe-Cr-Mo-Cu N08825, N08827 Ni-Fe-Cr-W N06674 Ni-Mo N10665, N10675, N10629 Ni-Mo-Cr-Fe N10242, N10624 1.1.1 The nickel-iron-chromium alloys are UNS N08120, UNS N08800, UNS N08810, and UNS N08811. Alloy UNS N08800 is normally employed in service temperatures up to and including 1100 °F (593 °C). Alloys UNS N08810, N08120, and UNS N08811 are normally employed in service temperatures above 1100 °F (593 °C) where resistance to creep and rupture is required, and are annealed to develop controlled grain size for optimum properties in this temperature range. 1.1.2 Nickel-iron-chromium-tungsten alloy UNS N06674 is normally employed in service temperatures above 1100 °F (593 °C) where resistance to creep and rupture is required, and is annealed to develop optimum properties in this temperature range. 1.1.3 Nickel-chromium-molybdenum-columbium (UNS N06625) products are furnished in two grades of different heat-treated conditions: 1.1.3.1 Grade 1 (Annealed)— Material is normally employed in service temperatures up to 1100 °F (593 °C). 1.1.3.2 Grade 2 (Solution annealed)— Material is normally employed in service temperatures above 1100 °F (593 °C) where resistance to creep and rupture are required. Note 1: Hot-working or reannealing may change properties significantly, depending on working history and temperatures. 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 Safety Data Sheet (SDS) 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.
