ASTM A36 steel plate is the most widely used hot rolled steel product. As a kind of carbon structural steel product, its relative products are round bar steel, angle steel, and steel sections such as I Beams, H beams, and C channels. The final product of hot rolled ASTM A36 steel plate has rough surface, which is convenient for subsequent processing such as machine processing.
ASTM A36 steel plate chemical composition:
| Thickness | Up thru 3/4 | Over 3/4 thru 1-1/2 | Over 1-1/2 thru 2-1/2 | Over 2-1/2 thru 4 | Over 4 |
| Carbon | 0.25 | 0.25 | 0.26 | 0.27 | 0.29 |
| Manganese | -- | 0.80/1.20 | 0.85/1.20 | 0.85/1.20 | 0.85/1.20 |
| Phosphorus | 0.04 | 0.04 | 0.04 | 0.04 | 0.04 |
| Sulphur | 0.05 | 0.05 | 0.05 | 0.05 | 0.05 |
| Silicon | 0.40 max | 0.40 max | 0.15/.40 | 0.15/.40 | 0.15/.40 |
| Copper min % when copper steel is specified | 0.20 | 0.20 | 0.20 | 0.20 | 0.20 |
| Note: For each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted, up to the maximum of 1.35%. | |||||
Typical ASTM A36 steel plate mechanical properties:
