SA 283 Gr C, or ASTM A283 Grade C, is a carbon steel plate used in general structural applications. Here are the typical material properties of SA 283 Gr C:
Carbon (C): 0.24% max
Manganese (Mn): 0.90% to 1.40%
Phosphorus (P): 0.035% max
Sulfur (S): 0.040% max
Tensile Strength: 55,000 - 75,000 psi (380 - 515 MPa)
Yield Strength: 30,000 psi (205 MPa) minimum
Elongation in 8 in. (200 mm): 22% minimum
Elongation in 2 in. (50 mm): 25% minimum
Density: 7.85 g/cm³ (0.284 lb/in³)
Electrical Resistivity: 0.0000159 ohm-cm
SA 283 Gr C is typically used for:
Structural applications in buildings and bridges.
General construction purposes.
Machinery and equipment.
These properties make SA 283 Gr C suitable for a wide range of structural applications where good weldability and moderate strength are required. It is commonly bolted, riveted, or welded in construction projects due to its ease of fabrication and relatively low cost compared to higher strength steels.
