A billet is rolled out of bloom, has at least asgm mm X 40 mm cross-section. Workmanship, Finish and Appearance The B and G scale hardness values apply to metal 0. Billets are rolled into bars, rods. The ingot is soaked at the hot astk temperature and then rolled into blooms or billets or slabs. In case of disagreements, the chemical composition is determined following appropriate methods listed here.


The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. When all the elements in Table 1 are analyzed, their sum shall be as follows: Although no minimum grain size is required, this material shall be fully recrystallized.
