| NOTE: | For standard H grades, the maximum carbon content of the comparable standard steel is used when considering cold shearing limitations. |
| a | All sizes in this carbon range should be thermally treated before cold shearing. |
| b | Refer to Table 1-4 for cross-sectional area and metric equivalents. |
