One class, B, is cold drawn with higher than normal heavy drafts to provide higher strength levels, and four grades provide improved machinability. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents, therefore, each system must be used ast, of the other.
Combining values from the two systems may result in nonconformance with the speci? Referenced Documents stresses, and then cooling slowly enough to minimize the development of adtm residual stresses.
