Type of pipe and tube:			Nickel-Iron-Chromium Alloy Seamless Pipe and Tube B407 grade UNS N08890
Standard Specification for Nickel-Iron-Chromium Alloy Seamless Pipe and Tube This standard is issued under the fixed designation B407; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.


Scope
This specification covers UNS N08120, UNS N08800, UNS N08801, UNS N08810, UNS N08811, UNS N08890, and UNS N06811 in the form of cold-worked and hot-finished annealed seamless pipe and tube. Alloys UNS N08800 and UNS N06811 are normally employed in service temperatures up to and including 1100°F (593°C). Alloys UNS N08120, UNS N08810, UNS N08811, and UNS N08890 are normally employed in service temperatures above 1100°F (593°C) where resistance to creep and rupture is required, and they are annealed to develop controlled grain size for optimum properties in this temperature range. 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. The following safety hazards caveat pertains only to the test method portion, of this specification.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.

Dimensions and Permissible Variations
Diameter and Wall Thickness: The permissible variations in the outside and inside diameter and wall thickness of pipe and tube shall not exceed those prescribed, as applicable. Permissible variations given are applicable only to two dimensions. Thus, if outside diameter and wall are specified, the inside diameter may not conform to the permissible variations shown. Similarly, if outside diameter and inside diameter are specified, the wall may not conform to the permissible variations shown. Length—When pipe or tube is ordered cut-to-length, the length shall not be less than that specified, but a variation of +V8 in. (3.2 mm) will be permitted for cold-worked material and +3/16 in. (4.8 mm) for hot-finished tube, except that for lengths over 30 ft (9.1 m), a variation of +V4 in. (6.4 mm) will be permitted. For small-diameter and light-wall tube, material shall conform to the applicable requirements. Straightness—Cold-drawn material shall be reasonably straight and free of bends and kinks. For small-diameter and light-wall tube, material shall conform to the applicable requirements. The camber (depth of chord) of hot-finished tube 5 in. (127 mm) in outside diameter and under shall not exceed 0.01 in./ft (0.8 mm/m). For sizes over 5 in. in outside diameter, the camber shall not exceed 0.015 in./ft (1.4 mm/m).

^A The permissible variations in this table apply to individual measurements, including out-of-roundness (ovality), except for the following conditions. 1)Thin-Wall Pipe and Tube—For thin-wall pipe and tube having a nominal wall thickness of 3 % or less of the nominal outside diameter, in all conditions (temper), the mean outside diameter or mean inside diameter shall conform to the permissible variations of this table, and individual measurements (including ovality) shall conform to the plus and minus values of this table, with the values increased by 0.5 % of the nominal outside diameter. 2)Annealed Pipe and Tube Over 4 1/2 in. (114.3 mm) in Nominal Outside Diameter—For annealed pipe and tubing over 4 1/2 in. (114.3 mm) in nominal outside diameter with a nominal wall thickness greater than 3 % of the nominal outside diameter, the mean outside diameter or mean inside diameter shall conform to the permissible variations of this table, and individual measurements shall not exceed twice the permissible variations of this table. ^B For pipe and tube, in all tempers, with an inside diameter of less than V2 in. (12.70 mm) which cannot be successfully drawn over a mandrel, the inside diameter shall be governed by the outside diameter and the wall thickness variations. ^C For pipe and tube in all tempers with an inside diameter less than 50 % of the outside diameter, which cannot be successfully drawn over a mandrel, the inside diameter may vary over or under by an amount equal to 10 % of the nominal wall thickness and the wall thickness may vary ±15 %. ^D Eccentricity—The variation in wall thickness in any one cross section of any one cold-finished pipe or tube shall not exceed ±10 % of the actual (measured) average wall of that section (defined as the average of the thickest and the thinnest wall in that section). ^E For tube 5 in. (127.0 mm) and under in outside diameter the tolerance on the outside diameter applies for individual measurements and includes ovality. For tubes over 5 in. (127.0 mm) in outside diameter the mean outside diameter shall conform to the permissible variations of this table and individual measurements shall not exceed twice the permissible variations of this table. ^FThe diameter tolerances for tube with machined outside and inside diameters shall be +0.031 in.
