| Note: | For standard H grades, the maximum carbon content of the comparable standard steel is used when considering cold shearing limitations. |
| a | Refer to Table 1-4 for cross-sectional area and metric equivalents. |
| b | Sizes 1 inch2 and smaller should be cold shearing quality or thermally treated before cold shearing. Producers should be consulted for flat sizes under 3/4 inch thickness. |
| c | All sizes in this carbon range should be cold shearing quality or thermally treated before cold shearing. |
