ASTM A283 Steel Plate

ASTM A283 is a standard specification for low and intermediate tensile strength carbon steel plates. ASTM A283 steel plates are used in various structural applications and the manufacture of machinery parts. Here are some key points about ASTM A283 steel plates:

Grades:

A283 Grade A: Low and intermediate tensile strength carbon steel plates.

A283 Grade B: Similar to Grade A but with slightly higher mechanical properties.

A283 Grade C: Higher carbon content than Grades A and B, providing increased strength.

Chemical Composition (Percentage by weight):

Carbon (C): 0.24% max

Manganese (Mn): 0.90% max

Phosphorus (P): 0.035% max

Sulfur (S): 0.040% max

Silicon (Si): 0.15-0.40%

Mechanical Properties:

Tensile Strength:

Grade A: 45,000 - 60,000 psi (310 - 415 MPa)

Grade B: 50,000 - 65,000 psi (345 - 450 MPa)

Grade C: 55,000 - 75,000 psi (380 - 515 MPa)

Yield Strength:

Grade A: 24,000 psi (165 MPa) min

Grade B: 27,000 psi (185 MPa) min

Grade C: 30,000 psi (205 MPa) min

Elongation in 8 inches:

Grade A: 27%

Grade B: 25%

Grade C: 22%

Elongation in 2 inches:

Grade A: 38%

Grade B: 28%

Grade C: 20%

Applications:

ASTM A283 steel plates are commonly used in the construction of buildings, bridges, and other structures where low to intermediate tensile strength carbon steel is required.

Widely used in the manufacturing of pressure vessels and boilers.

Additional Information:

Weldability: ASTM A283 steel plates exhibit good weldability, making them suitable for various welding processes.

Corrosion Resistance: While not corrosion-resistant, proper coatings can be applied to enhance corrosion resistance in different environments.

Always refer to the latest ASTM A283 standard specifications for precise and up-to-date information on chemical composition, mechanical properties, and application guidelines when using ASTM A283 steel plates in your projects.
