(Specification)Standard Specification for Nickel-Iron-Chromium-Molybdenum-Columbium Stabilized Alloy (UNS N08700) Plate, Sheet, and Strip
Standard Specification for Nickel-Iron-Chromium-Molybdenum-Columbium Stabilized Alloy (UNS N08700) Plate, Sheet, and Strip
ABSTRACT
This specification covers nickel-iron-chromium-molybdenum-columbium stabilized alloy (UNS N08700) plate, sheet, and strip in the solution-annealed condition. Minor cold working such as flattening or temper rolling may be performed after the final solution annealing treatment. The material shall conform to the chemical requirements for nickel, iron, chromium, molybdenum, columbium, carbon, silicon, manganese, phosphorus, sulfur, and copper. The material shall conform to the mechanical property requirements for tensile strength, yield strength, elongation, and Rockwell hardness. The material shall be free of injurious imperfections and shall correspond to the designated finish for sheet, strip, and plate. Test methods (chemical analysis, tension test, corrosion test) for chemical composition and mechanical properties determination shall be performed in accordance to referenced ASTM documents itemized herein.
SCOPE
1.1 This specification covers nickel-iron-chromiummolydenum-columbium stabilized alloy (UNS N08700)* plate, sheet, and strip in the solution-annealed condition.
1.2 The values stated in inch-pound units are to be regarded as 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 Material Safety Data Sheet 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.
