ASTM A573 Grade 58 (A573Gr58) Carbon Steel Plate is a structural carbon steel plate known for its improved toughness and moderate strength. It is commonly used in applications requiring better impact resistance than standard carbon steels like ASTM A36 or A283.

This steel plate is ideal where higher toughness and moderate strength are required without needing high-alloy or high-strength materials.

Key Features of ASTM A573 Grade 58 (A573Gr58):

1. Strength: Minimum yield strength of 50 ksi (345 MPa) and tensile strength of 65-85 ksi (450-585 MPa).

2. Improved Toughness: Designed for better notch toughness at low temperatures compared to standard carbon steels.

3. Weldability & Formability: Good weldability and formability, making it suitable for structural applications.

4. Heat Treatment: Typically supplied in normalized condition to enhance grain structure and toughness.

Construction field: Used for building large-scale structures such as bridges and high-rise buildings, meeting requirements for structural strength and safety.

Mechanical manufacturing: Suitable for producing various mechanical components, such as machine bases and workbenches, capable of withstanding heavy loads and stress.

Shipbuilding: Ideal for ship hull structures, decks, and other parts, offering excellent toughness and impact resistance to adapt to marine environments.

Pressure vessels: Can be used to manufacture various pressure vessels, such as storage tanks and reactors, ensuring safe operation under harsh conditions like high pressure and high temperature.

Comparisons:

Vs. A36: A573Gr58 offers better toughness and is normalized for improved properties.

Vs. A572Gr50: A573Gr58 has better impact resistance but slightly lower yield strength.

Vs. A516Gr60/65: A573Gr58 is not a pressure vessel steel but offers better toughness.

Available Sizes & Forms:

Thickness: Typically ranges from 3/16" to 4" (5mm to 100mm).

Width & Length: Standard mill sizes, often up to 120" (3m) wide and 480" (12m) long.
