19、ted to a hardness test with a Brinell Hardness Tester. The sample, 10 percent minimum representative of extreme furnace envi- ronment, shall be selected from each heat treat batch when a batch type furnace is used for final heat treatment. When a batch type furnace is used for final heat treatment,
20、the following shall be substituted for a batch. For identi- fication purposes, any quantity of nose castings, but not to exceed 4 hours production of the final heat treatment that have been subjected to final heat treatment in the same furnace, at the same temperature for the same length of time or
21、conveyor speed, shall be considered a heat treat- ment batch. The heat treatment batch thus constituted shall form the basis for selecting sample castings for the tension test hereinafter prescribed. The test shall be performed as specified in 4.4.1, using equipment in accordance with 4.3.4. 4.3.3.2
22、 Tension Test on Nose - Major Defect.-Two (2) nose castings from each heat treatment batch, one of the hardest and one of the softest, as determined by 4.3.3.1, shall be subjected to this test. Failure of one or more tension test specimens to comply with the physical require- ments of the applicable
23、 drawing shall be cause for rejection of the batch represented by the specimen. The test shall be performed as specified in 4.4.2, using equipment in ac- cordance with 4.3.4. 4.3.3.3 Hardness Test on Body - Major Defect.-To in- sure compliance with the mechanical properties requirements, each nose c
24、asting from a sample shall be subjected to a hardness test with a Brinell Hardness Tester.
