1.1 This specification covers tool steel compositions for usable shapes cast by pouring directly into suitable molds and for master heats for remelting and casting. Note 1-A master heat is defined as any single heat of steel of certified analysis which has been processed into suitable form (shot, ingot, etc.) for remelting. A uniform blend of master heats is also acceptable for remelting. This blend is defined as a master heat lot and its average chemical composition shall be certified.1.2 Nine grades, CA-2, CD-2, CD-5, CM-2, CS-5, CS-7, CH-12, CH-13, and CO-1, are covered in this specification. Note 2-The committee formulating this specification has included air- and oil-hardening grades of tool steel that have been extensively used. Other compositions will be considered for inclusion as the need arises. |
