3.General Requirements for Delivery
3.1 Plates furnished under this specification shall conform
to the applicable requirements of the current edition of Specification A6/A6M unless a conflict exists in which case this specification shall prevail.
4. Materials and Manufacture
4.I The steel shall be killed and conform to the require ments for fine austenitic grain size in Specification A6/A6M.
5. Heat Treatment
5.1 Except as allowed by 5.2, plates shall be heat treated to conform to the tensile and hardness requirements given in Table 2 by heating to not less than 1650°F[900°C]， quenchin in water or oil, and tempering at not less than 1150°F (620°C The heat-treatment temperatures shall be reported in the test report。
5.2 Plates ordered without the heat treatment specified in 5.1 shall be stress relieved by the manufacturer, and subsequent heat treatment of the plates to conform to 5.1 shall be the responsibility of the purchaser.
6. Chemical Composition
6.1 The heat analysis shall conform to the requirements given in Table 1.
6.2 The product analysis shall conform to the requirements given in Table, subject to the product analysis tolerances in Specification A6/A6M.
7. Mechanical Properties
7.1 Tension Test – The plates as represented by the tension test specimens shall conform to the tensile requirements given in Table 2.
7.2 Hardness Test – For plates% in [10 mm] and under in thickness, a Brinell hardness test may be used instead of tension testing each plate, in which case a tension test shall be made from a corner of each of two plates per lot. A lot shal consist of plates from the same heat, thickness, prior condition and scheduled heat treatment and shall not exceed 15 tons [15 Mg] in weight Imass).A Brinell hardness test shall be made on each plate not tension tested and the results shall conform to the hardness requirements given in Table 2.
8. Number of Tests
8.1 Except as allowed by 7.2, one tension test shall be taken from a corner of each plate as heat treated.ASTM A514-14 pdf free download.
