Products Description
ASTM A283 Gr C consists of four grades of material (A, B, C, & D) of carbon steel plate of structural quality for general application.
ASTM A36 covers carbon steel plate, shape, and bar of structural quality for use in riveted, bolted, or welded construction of bridges and buildings and for general structural purposes.
From material scope, ASTM A36 and ASTM A283 are the carbon steel of structural quality for general application.
ASTM A283 grade C steel VS A36 steel in chemical composition %
| Grade | C (t≤16mm) | Si | Mn | P | S | Cu |
| A36 | 0.26 max | 0.40 max | - | 0.04 max | 0.05 max | 0.20 min |
| A283 grade C | 0.24 max | 0.04 max | 0.09 max | 0.035 max | 0.04 max | 0.20 min |
ASTM A283 grade C VS A36 steel in mechanical properties
| Grade | Yield strength ReH/(N/mm2) (t≤16mm) min | Tensile strength Rm/(N/mm2) (3mm≤t≤16mm) | Elongation A/%(3mm≤t≤40mm) min |
| A36 | 250 | 400-550 | 23 |
| A283 grade C | 205 | 380-515 | 25 |
ASTM A283 grade C and A36 steel aren't exactly the same, but they are very close. Based on the weldability, it can consider that A36 steel can be used as alternative substitution of ASTM A283 grade C.
However, if you decide by A36 steel as substitution to ASTM A283 grade C, further Engineering approval is required.
