3. General Conditions fo- Delivery
3.1 Material furnished to this specification shall conform to the requirements of specifications ASTM A781/A781 M, including any supplementary requirements that are indicated in the order.
4. Chemical Composition
4.1 The composition shall comply with the reqLMrements of Table 1.
4.2 When not specified in Table 1 the content 04 carbon, manganese, S4IICOfl, and alloying elements may, by aeement, be prescribed by the purchaser. It not specified, the content may be selected by the manufacturer to obtain the required mechanical properties or hardenability.
5. Neat Treatment—All castings shall be supplied m the heat treated condition. The heat treatment procedure may be specified by the purchaser ii a written agreement with the supplier. Unless otherwise specified, the supplier may choose to heat treat the castings by one or more of the following processes; annealing, normalizing, normalizrng and tempering or quenching and tempering,
In the event of a change in the heat treatment procedure the requirements of Section 6 must be met
6. Mechanical Properties
6.1 MechanIcal testing from separately cast lest bars shall be carried out in accordance with ASTM A370
The mechanical properties shall comply with the requirements of Table 1. The test bars shall be heat treated in production furnaces. Test bars shall be heat treated to the same procedure as the castings they represent
6.2 Product Testing—Subject to agreement between the purchaser and supplier, test bars may be taken from the castings. The location and the required mechanical properties are subleci to agreement between the purchaser and supplier
7. Frequency of Testing
7.1 Following the satisfactory achievement of the required mechanical properties of ten consecutive heats from any one grade, succeeding heats from the same grades may be qualified by hardness testing providing they tall within the range of compositions of the original 10 heals. The castings in each heat will be accepted by hardness testing of one test bar from each heat,
It the purchaser wishes to substitute complete mechanical testing then supplementary requirement 10.1 should be specified.
7.2 Retests—If any specimen shows defective machining, or exhibits flaws, it may be discarded and another substituted from the same heal.
8. InspectIon
8.1 Minor dlscontinultles—The surface of the casting shall be free of adhering sand, scale, cradis and hot tears as determined by visual exanination Other surface discontinuities shall meet the visual acceptance standards specified in the order. Practice ASTM A 802/A 802M or other visual standards such as MSS SP-55 may be used to define acceptable surface dlscontinudies and fInish. Unacceptable visual surface discontinuitles shall be removed and their removal verified by visual examination of the resultant cavities.
8.2 Peenlng. plugging and impregnating of castings are not allowed.
8.3 MarkIng—The manufacturers name or identification mark and the pattern number shall be cast or stamped on all castings. When further specified, the heat numbers or serial numbers shall be marked on the Individual castings.
8.4 Inspection by the Purchaser—The manufacturer shall afford the purchasers inspector all reasonable facilities necessary to satisfy him that the material is being produced and supplied in accordance with this specification. Foundry inspection by the purchaser shall not interfere with the manufacturer’s operations’. All tests and inspections (except product analysis) shall be made at the place of manufacture unless otherwise agreed to.
