Property | Grade B | Grade C |
Yield strength (ksi/MPa) | 46 ksi / 320 MPa | 50 ksi / 345 MPa |
Tensile strength (ksi/MPa) | 58 ksi / 400 MPa | 62 ksi / 430 MPa |
Elongation (%) | 20% | 18% |
Brinell hardness (HB) | 120–150 | 130–160 |
Typical dimensions: 2" x 1" up to 12" x 8", thicknesses 0.065" – 0.5".
Standard lengths: 6–12 m.
Dimensional tolerances and manufacturing per ASTM A500-23.
- ASTM A500 Grade B: similar to A36 in minimum tensile strength.
- ASTM A500 Grade C: higher strength, comparable to high-strength steels.
ASTM A500 Grade B/C rectangular tubing is a reliable and versatile profile. Grade B is recommended for general applications, while Grade C is used when higher mechanical demand is required.
