ASTM A633 Grade A is a normalized high-strength low-alloy structural steel with the following properties:
| Property | Value |
|---|---|
| Yield Strength (min) | 290 MPa (42 ksi) |
| Tensile Strength | 430-570 MPa (62-83 ksi) |
| Elongation in 8″ (min) | 20% |
Chemical Composition:
| Element | Percentage |
|---|---|
| Carbon (max) | 0.18% |
| Manganese | 1.00-1.35% |
| Silicon | 0.15-0.50% |
| Phosphorus (max) | 0.035% |
| Sulfur (max) | 0.04% |
ASTM A633 Grade A steel is commonly used in:
ASTM A633 Grade A is normalized by heat treatment to achieve a fine austenitic grain size. Available dimensions include:
| Thickness (mm) | Width (mm) | Length (mm) |
|---|---|---|
| 6 – 100 | 1500 – 4050 | 3000 – 15000 |
ASTM A633 Grade A has excellent weldability. It is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized.
| Grade | Yield Strength (min MPa) | Tensile Strength (MPa) |
|---|---|---|
| A | 290 | 430-570 |
| C | 345 (up to 65 mm thickness) | 485-620 |
| D | 345 (up to 65 mm thickness) | 485-620 |
| E | 415 (up to 100 mm thickness) | 550-690 |
ASTM A633 Grade A offers improved notch toughness compared to as-rolled materials of similar strength, making it suitable for low-temperature applications. Its normalized structure provides consistent properties throughout the material.
