Table Notes: Values represent properties obtained from separately cast test bars and are derived from ASTM B26. Unless otherwise specified, the average ultimate, yield and elongation values of specimens cut from castings shall be not less than 75% of the ultimate and yield strength values and not less than 25% of the elongation values given above. F temper indicates the as cast condition. Hardness values are given for information only and are not required for acceptance. |
