ASTM B-407-87 / ASME SB-407
SPECIFICATION FOR NICKEL-IRON-CHROMIUM ALLOY SEAMLESS PIPE AND TUBE
 

1.Scope
1.1 This specification covers UNS N08800, UNS N08801, UNS N08810,and UNS N08811 in the form of cold-worked and hot-finished annealed seamless pipe and tube. Alloy UNS N08810 is normally emloyed in service temperatures up to and including 1100F (593?). Alloys UNS N08811 are normally employed in service temperatures above 1100F (593?) where resistance to creep and rupture is required, and they are annealed to develop controlled grain size for optimum properties in this temperatue range. 

1.2 The values ststed in inch0pound units are to be regarded as the standaed. The values given in parentheses are for information only. 

1.3 The folloeing safety hazards caveat pertains only to the test method portin, Sectiom 13, od this specofoaction. This standsrd does not purport to address all of the responsibility of the user of this sandard to establish the applicability of regulatory limitations prior to use.

Hardness values, indicative of tensile strength, re shown for information only. All tests are subject to confirmation by tension tests. For hardness conversions see Hardness Conversion Tables E 140.

This condition is sometimes designated as "No.1 Temper."

The minimum tensile strength value applies only to tubing in straightlengths.

This condition is sometimes designated as "No. 2 Temper."

This condition is sometimes designated as "No.3 Temper."

X2.2.2 Cold-Finished, Annealed, and Pickled (Not Ground) - Outside and inside diameter will have dull, matee (pickled) surfaces. Available in sizes 1/2 to 6 5/8 in (12.7 to 168mm) inclusive, in outside diameter in both normal and heavy-wall tube, and pipe sizes, all schedules, of corresponding outside diameter dimensions. 

X.2.3 Hot-Finished Tube : 
X.2.3.1 Hot-Finished, or Hot-Finished Annealed, (Not Pickled) Tube - Has an oxide surface resulting from the hot-finishing operation. Intended generally for machined parts where the oxide surface will be removed. 
X2.3.2 Hot-Finished, or Hot-Finished Annealed, (Pickled) Tube - Has the oxide surface removed on both the outside and inside diameters by picking. Surface may be spot ground for removal of minor surface imperfections at the manufacturer's option. 
X2.3.3 Hot-Finished, or Hot-Finished Annealed, (Machined Outside and Inside Diameters) Tube - The outside and inside diameter surfaces are machined to specified dimensions. Minor surface imperfections may be spot ground for removal, at the manufacturer;s option.

Ovality, Normal Wall Tube:
Annealed (No.1) Temper - Ovality will be held within 2% of the theoretical average outside diameter.
Ovality, Light-Wall Tube:
Annealed (No.1) Temper - Ovality will be held within 2% of the theoretical average outside diameter.
Wall Tolerances, Light-Wall Tube-The plus and minus wall tolerance shown in the table shall apply down to and including 0.005 in. (0.12 mm) in wall thickness. For wall thicknesses less than 0.005 in. (0.1 mm) the tolerance shall be ±0.0005 in. (0.0127 mm).
Random Lengths:
Where nominal random lengths on tubing 1/8 in. (3.18mm) and larger in outside diameter are specified, a length tolerance of ±3 1/2 ft (106cm) applies to the nominal length. This is a totalspread of 7 ft (210cm).
Random lengths in sizes 1/8 in. (3.18 mm) and larger in outside diameter shall be subject to a length range of 5 to 24 ft (150 to 730 cm). Long random lengths are subject to a range of 15 to 22 ft (457 to 670cm).
Random lengths in sizes up to but not including 1/8 in. (3.18 mm) in outside diameter, and fragile lightwall tubes over this outside diameter are subject to the length range of 1 to 15 ft (30 to 457cm).
Cut lengths - Tolerances on cut lengths shall be as follows :

Over 300 up to 31.75, incl 4.76 0

Straightness - Round tubing is subject to a straightness tolerance of one part in 600[equivalent to a depth of are of 0.030 in.(0.762 mm) in any 3 ft(91cm) of length].

Eccentricity-Eccentricity as defined in Table 3, Footnote D shall belimited to ±1-% of the specified wall or calculated average wall. HWhen specified, the tolerance spreads of this table may be applied as desired. However, when not specified, the tolerances in this table will apply. It should be noted that inside diameter tolerances are based upon the outside diameter range.
