ASTM A573 Grade 58 Structural Steel Plate for Storage Tanks

A573Gr58 steel sheet of improved toughness owned the minimum yield strength at 220 MPa,and the tensile strength of A573Gr58 steel plate shall be within 400-490Mpa.

A573/A573M specification covers structural quality carbon manganese silicon steel plates in three tensile strength range for A573 Grade 58,A573 Grade 65 and A573 Grade 70.A537Gr58 is intended primarily for service at atmospheric temperatures where improved notch toughness is important.

The steel of A573Gr58 shall be made by one or more of the following processes as open hearth,basic oxygen or electric furnace.

ASTM A573 Grade 58 steel plate is primarily used in structural applications that require improved toughness and reliable performance at atmospheric temperatures. Its balanced combination of strength (yield strength ≥ 220 MPa, tensile strength 400–490 MPa) and ductility makes it suitable for various industries.

Typical applications include:

• Storage tanks and pressure vessels: Ideal for low-pressure tanks and welded storage containers where notch toughness ensures safety.

• Bridges and building structures: Applied in welded and bolted structural members that demand high toughness to resist brittle fracture.

• Machinery frames and supports: Used in heavy-duty construction machinery, cranes, and industrial frames requiring stability under impact loads.

• Transportation equipment: Suitable for truck frames, railcars, and shipping containers due to its reliable weldability and strength.

• Energy and infrastructure projects: Common in wind turbine towers, support columns, and power plant structural components.

A573 Grade 58 plate's combination of moderate strength, high toughness, and good weldability makes it an excellent choice for structural fabrication in construction, manufacturing, and energy sectors.
