| Over 4 to 8 in. [100 to 200 mm], incl | 0.27 |
| Over 8 in. [200 mm] | 0.27 |
| ManganeseB: | |
| 1⁄2 in. [12.5 mm] and under: | |
| Heat analysis | 0.60-0.90 |
| Product analysis | 0.55-0.98 |
| Over 1⁄2 in. [12.5 mm]: | |
| Heat analysis | 0.85-1.20 |
| Product analysis | 0.79-1.30 |
| Phosphorus,maxA | 0.025 |

A Applies to both heat and product analyses.
B For each reduction of 0.01 percentage point below the specified maximum for carbon, an increase of 0.06 percentage point above the specified maximum for manganese is permitted, up to a maximum of 1.50 % by heat analysis and 1.60 % by product analysis.
C Grade 60 plates 1⁄2 in. [12.5 mm] and under in thickness may have 0.85–1.20 % manganese on heat analysis, and 0.79–1.30 % manganese on product analysis.
Tensile Requirements
| Grade60[415] | |
| Tensile strength, ksi [MPa] | 60–80 [415–550] |
| Yield strength, min,A ksi [MPa] | 32 [220] |
| Elongation in 8 in. [200 mm], min, %B | 21 |
| Elongation in 2 in. [50 mm], min, %B | 25 |
A Determined by either the 0.2 % offset method or the 0.5 % extension-under-load method.
B See Specification A20/A20M for elongation adjustment.
