Also includes scrapped machinery and fabricated items, chips, and turnings. If astj second casting fails, all remaining castings shall be radiographed in only the rejectable areas found on the first and second castings.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

Since these grades possess varying degrees of suitability for service in corrosive environments, it is the responsibility of the purchaser to determine which grade shall be furnished. A As-cast Quench in water or rapid cool by other means as agreed upon by the manufacturer and purchaser.
