ASTM A285GrA/A285 Grade A steel plate is a kind of pressure vessel steel plate designed for the fabrication of welded pressure vessels and boilers. It is a low-to-intermediate tensile strength steel that is widely used in the fabrication of petroleum, chemical, gas separation, and storage containers.

Chemical Composition:

The chemical composition of ASTM A285GrA/A285 Grade A is strictly controlled to ensure the proper balance of strength and toughness. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.17%

· Manganese (Mn): 0.90-1.50%

· Phosphorus (P): ≤ 0.035%

· Sulfur (S): ≤ 0.035%

· Silicon (Si): 0.13-0.45%

Mechanical Properties:

The mechanical properties of ASTM A285GrA/A285 Grade A are as follows:

· Tensile Strength: 45-65 ksi (310-450 MPa)

· Yield Strength: ≥ 24 ksi (165 MPa)

· Elongation in 2 inches (50 mm): ≥ 27%

Heat Treatment:

The steel plates are normally supplied in the as-rolled condition. However, they can be normalized if required by the customer. Normalizing is a heat treatment process that improves the mechanical properties of the steel, especially toughness.

Low-Temperature Impact Test:

ASTM A285GrA/A285 Grade A steel plates are often subjected to low-temperature impact tests to ensure their suitability for use in low-temperature environments. The typical impact energy value at -20°F (-29°C) is ≥ 20 ft-lbs (27 J).
