3. Ordering Information
3.1 Orders for material under this specification should include the following, as required, to describe the desired material adequately:
3.1.1 Quantity (weight in pounds or pieces),
3.1.2 Name of material (chromium-nickel steel plate, sheet, or strip),
3.1.3 Grades or types (Table 1),
3.1.4 Finish (Table 2),
3.1.5 Untreated, heat-treated, or precipitation-hardened condition (see 4.1),
3.1.6 Width and length required (in inches [mm] or by another suitable method), and
3.1.7 Name and address of purchaser.
4. Condition
4.1 The material is available as follows:
4.1.1 Untreated—Material received without further heat or cold treatment (see 6.2).
4.1.2 Heat-Treated—Material received after application of heating and/or cooling operations, in which case the responsible producer or processor shall designate the condition upon agreement with the purchaser.
4.1.3 Precipitation-Hardened—Material received after application of a suitable heat treatment followed by a suitable aging treatment, in which case the responsible processor or producer shall designate the condition upon agreement with the purchaser.
5. Heat Treatment
5.1 All heat-treated material must be capable of meeting the requirements of this specification in its heat-treated condition. Unless otherwise specified in the purchase order, the heat treatment to which the material is to be subjected shall be the responsibility of the producer or processor.
6. Chemical Requirements
6.1 The material shall conform to the chemical requirements specified in Table 3.
6.2 If material is received in the as-rolled condition and is to be subsequently heat treated, the heat treating furnace atmosphere should provide a inert atmosphere. This is to prevent the formation of oxides, carbides, and other undesired phases.
7. Mechanical Requirements
7.1 The material shall conform to the mechanical requirements specified in Table 4.
8. Fabrication
8.1 The fabrication practices of the manufacturer should be in keeping with good metallurgical and engineering practice.
9. Retests
9.1 If any retest is conducted that involves heat treatment, the results shall meet the requirements of this specification in the condition in which the material is supplied.
10. Test Methods
10.1 Tests shall be made in accordance with the referenced Test Methods and Definitions.
11. Rejection and Rehearing
11.1 Rejection—Material that fails to meet the requirements of this specification shall be rejected and abandoned at once.
11.2 Rehearing—Material that fails to meet the requirements of this specification may be returned to the source of supply for rehearing upon agreement between the responsible processor or producer and the purchaser.
12. Certification
12.1 Upon request and for a fee, the processor or producer shall furnish a certificate that the material supplied has been tested in accordance with the requirements of this specification and has been found to meet its requirements.
