28、 2.9. Precipitation Heat Treatment9.1 When material is purchased in the TB00 (A) or the TD04 (H) tempers, the precipitation heat treatment is performed by thepurchaser.9.2 Conformance to the TF00 (AT) and TH04 (HT) specification limits shown in Table 2, for products supplied in the TB00 (A)or the TD
29、04 (H) tempers, shall be determined by testing test specimens heat-treated at a uniform temperature of 850 to 900F forthe times shown in Table 3.9.3 End products may be heat-treated at other times and temperatures for specific applications. These special combinations ofproperties such as increased d
30、uctility, dimensional accuracy, and endurance strength may be obtained by special precipitation-hardening heat treatments. The mechanical requirements of Table 2 do not apply to such special heat treatment. Specific testrequirements as needed shall be agreed upon between the manufacturer or the supp
31、lier and the purchaser of the end product.9.4 TF00 (AT) and TH04 (HT) tempers as standard mill-hardened products has been precipitation heat-treated and tested by themanufacturer. An appropriate time and temperature has been used to produce properties within the specification limits shown inTable 2.
32、 Table 3 does not apply. Further thermal treatment of these tempers is not normally required.9.5 Material may be supplied with nonstandard properties. Table 2 values would not apply. Specific test requirements as neededshall be agreed upon between the manufacturer or supplier and the purchaser of th
