Structural, Carbon & HSLA Steel Plate

ASTM A573-70

A high-strength, low-carbon manganese-silicon structural steel specifically engineered for applications requiring superior strength and toughness, particularly in moderate-temperature service. This specification ensures excellent weldability and resilience, making A573-70 an ideal choice for critical infrastructure projects like bridges, buildings, storage tanks, and general structural fabrication where stability under varying thermal conditions is paramount.

As a high-strength steel plate, Grade 70 offers an optimal balance between high tensile performance and formability. If your project demands certified, reliable material compliant with major construction codes, look no further than our stock of genuine ASTM A573 Grade 70 steel.
