(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-chromium-molybdenum-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 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 and health practices, and determine the applicability of regulatory limitations prior to use.

9.1 Sheet—The material referred to as sheet shall conform to the variations in dimensions prescribed in Tables 4-9, inclusive.
9.2 Cold-Rolled Strip—The material referred to as cold-rolled strip shall conform to the permissible variations in dimensions
prescribed in Tables 10-13, inclusive.
9.3 Plate—The material referred to as plate shall conform to the permissible variations in dimensions prescribed in Tables

9.4 Edges for Cold-Rolled Strip :
9.4.1 The various types of edges procurable shall be as follows:
9.4.1.1 No. 1 Edge—Rolled edge, contour as specified.
9.4.1.2 No. 3 Edge—An edge produced by slitting.
9.4.1.3 No. 5 Edge—Approximately square edge produced by rolling or filing, or both, after slitting.
10. Workmanship, Finish,Finish and Appearance
10.1 The material shall be free of injurious imperfections and shall correspond to the designated finish as described as follows:
10.1.1 Sheet—The various types of finish procurable on sheet products shall be as follows:
10.1.1.1 No. 1 Finish— Hot rolled, annealed, and descaled; produced by hot rolling to specified thicknesses followed by
annealing and descaling (see 10.2).
10.1.1.2 No. 2D Finish— Dull, cold-rolled finish; produced by cold rolling to the specified thickness, annealing, and descaling.
The dull finish results from the descaling and pickling operations.
10.1.1.3 No. 2B Finish— Bright, cold-rolled finish; produced by giving a final light cold-rolled pass with polished rolls, to a
sheet that has been annealed and descaled.
10.1.1.4 No. 4 Finish— General-purpose polished finish. Following initial grinding with coarser abrasives, sheets are generally
finishedlastwithabrasivesapproximately120to150mesh.Sheetscanbeproducedwithoneortwosidespolished.Whenpolished
on one side only, the other side may be rough ground in order to obtain the necessary flatness.
10.1.1.5 Bright Annealed— Bright finish produced by cold rolling to thickness, then annealing in a protective atmosphere.
10.1.2 Strip—The type of finish procurable on cold-rolled strip shall be as follows:
10.1.2.1 No. 1 Finish— Cold rolled to specified thickness, annealed, and pickled (see 10.2).Appearance of this finish is a dull
gray.

Camber is the greatest deviation of a side edge from a straight line, and
measurement is taken by placing an 8-ft (2440-mm) straightedge on the concave
side and measuring the greatest distance between the sheet edge and the
straightedge.
