Chemical Composition6.1 The material shall conform to the requirements pre-scribed in Table 1 for

    17、 the alloy specified in the orderinginformation.6.2 These composition limits do not preclude the presenceof other elements. Limits for unnamed elements may beestablished and analysis required by agreement between themanufacturer or supplier and purchaser.6.3 Zinc, when given as the “remainder,” is t
