Characteristics of ASTM A573 Grade 58 Steel
Microalloying Design: Manufactured through fine-grain processing to enhance grain boundary strength and optimize toughness.
Toughness: Suitable for applications where improved notch toughness at room temperature is critical, such as in low-temperature environments or dynamic loading scenarios.
Cutting Process: CNC plasma or laser cutting is preferred for thicknesses ≤20 mm; flame cutting is recommended for thicknesses >30 mm.
Weldability: Carbon content control (≤0.23%) and manganese adjustment (0.6%-0.9%) ensure stable performance of welded joints, making it suitable for welded structures like bridges and pressure vessels.
