Steel castings — General technical delivery requirements
This document specifies the general technical delivery requirements for the supply of steel, nickel, and cobalt alloy castings, including the requirements for the selection and preparation of samples and test pieces. When a material or product standard differ from this delivery specification, the material or product standard applies. In the case of investment castings, ISO 16468 applies.
