6.1.4 Annealed wire Nickel-copper-aluminum alloy wire in the annealed
condition is intended for severe forming, cold heading, and roll threading
operations.
6.1.5 Spring temper wire Nickel-copper-aluminum alloy wire, spring temper in the as drawn condition is intended for coiling of helical springs which are to be aged hardened after coiling in order to obtain maximum
strength and hardness. Where helical springs are to be cold pressed, the cold pressing is to be done after coiling and aging.
6.2 Ordering data. Acquisition documents must specify the following:
a) Title, number, and date of this specification.
b) Form, condition, and surface finish of material required (see
1.2.1 and 1.2.2).
c) Issue of dodiss cited and if different than that listed in the dodiss, the specific issue of individual documents referenced (see 2.1.1, 2.1.2, and 2.2).
d) Whether a forging sketch is required (see 3.1.1). e) Size required (see applicable table).
f) If a product check analysis is required (see 3.2).
g) When hardness measurements may be utilized for forged rings and discs (see footnote 4 of table III.).
h) When tolerances other than those specified are permitted (see footnote 2 of table VII; footnote 6 of table XV; footnote 5 of table XVI and footnote 2 of table XVIII).
i) If optional ultrasonic inspection is required (see 3.7.1.2)
j) If optional liquid penetrant inspection is required (see
3.7.2).
k) The lengths required and whether cut-to-length, random mill lengths, nominal (stock) lengths, or multiples of specified lengths (see 3.9.1.3.1, 3.9.3.3.1 and 3.9.3.3.2).
l) If multiples of a specified length are ordered, whether a �
inch allowance should be made for each cut (see 3.9.1.3.1).
m) If edges are other than specified (see 3.9.1.4, 3.9.3.4.1,
3.9.3.4.2, and 3.9.3.4.3).
n) Forging dimensions (see 3.9.2).
o) If marking should be other than specified (see 3.10).
p) When mechanical tests are required for rod and bar intended for reforging (see 4.3.2.2).
q) If mechanical testing is to be done on material ordered in the unaged condition, to demonstrate its capability of being aged to meet the required mechanical properties, and, if desired, the heat treating procedure to be used on the test specimens (See 4.3.2.2 and 4.3.2.2.1).
r) The final heat treatment procedure to be used on the lot before being placed into service and on the slow strain rate tensile test specimens (see 4.3.6.1).
s) When the laboratory conducting the slow strain rate tensile test is selected by the purchaser (see 4.3.6.4.4 )
