ASTM A656 Grade 80 is a high-strength, low-alloy (HSLA) steel with the following properties:
| Property | Value |
|---|---|
| Yield Strength (min) | 550 MPa (80 ksi) |
| Tensile Strength (min) | 620 MPa (90 ksi) |
| Elongation in 2″ (min) | 15% |
| Elongation in 8″ (min) | 12% |
Chemical Composition (max %):
C: 0.18, Si: 0.60, Mn: 1.65, P: 0.025, S: 0.035, V: 0.08, Ni: 0.02, Nb: 0.10
ASTM A656 Grade 80 steel is commonly used in:
ASTM A656 Grade 80 is produced through controlled rolling or thermo-mechanical controlled processing. Available dimensions include:
| Product Type | Thickness (in/mm) | Width (in/mm) | Length (in/mm) |
|---|---|---|---|
| Mill Plate | 0.437 – 1.00 / 11.1 – 25.4 | 72 – 120 / 1800 – 3050 | 120 – 1020 / 3050 – 25910 |
| Temper Leveled Plate | 0.100 – 0.50 / 2.54 – 13 | 48 – 96 / 1200 – 2400 | 72 – 720 / 1800 – 18300 |
ASTM A656 Grade 80 has good weldability but requires careful attention to welding procedures. Common fusion and resistance welding methods can be used, but oxyacetylene welding is not recommended. Proper preheat and interpass temperatures should be maintained to prevent cracking.
| Grade | Yield Strength (min ksi) | Tensile Strength (min ksi) | Elongation in 2″ (min %) |
|---|---|---|---|
| Grade 50 | 50 | 60 | 23 |
| Grade 60 | 60 | 70 | 20 |
| Grade 70 | 70 | 80 | 17 |
| Grade 80 | 80 | 90 | 15 |
While ASTM A656 Grade 80 may have a higher initial cost compared to standard structural steels, its high strength-to-weight ratio allows for thinner sections and reduced overall weight in structures. This can lead to cost savings in material usage, transportation, and installation, particularly in large-scale projects.
