A283 Grade C Steel Properties

Plate ASTM A283 Grade C is a material in the American Society for Testing and Materials (ASTM) specification for low and intermediate tensile strength carbon steel plates. A283 Gr.C plates are commonly used in the construction of storage tanks and low-pressure temperature-controlled vessels.

If you have specific questions or if there's a particular aspect of A283 Grade C that you'd like more information on, feel free to provide more details. Whether it's about its properties, applications, or anything else related to A283 Grade C

A283 Grade C is a carbon steel plate with specified minimum yield strength of 24 KSI (kilo-pound per square inch) and tensile strength of 55 to 75 KSI. Here are some key properties of A283 Grade C:

1. Chemical Composition:

   • Carbon (C): 0.24% max
   • Manganese (Mn): 0.90% max
   • Phosphorus (P): 0.030% max
   • Sulfur (S): 0.030% max

2. Mechanical Properties:

   • Yield Strength (at 8 inches): 24 KSI min (165 MPa min)
   • Tensile Strength: 55-75 KSI (380-515 MPa)
   • Elongation: 22% min (in 8 inches), 25% min (in 2 inches)

3. Thickness and Availability:

   • A283 Grade C plates are typically available in thicknesses from 6 mm to 300 mm.

4. Usage and Applications:

   • A283 Grade C is commonly used for structural and constructional applications.
   • It is often utilized in the production of storage tanks, bridges, buildings, and other structures where welding is required.

5. Welding Considerations:

   • A283 Grade C is suitable for general-purpose structural steel welding.
   • Weldability is a critical consideration, and the material responds well to conventional methods.

6. Heat Treatment:

   • A283 Grade C is not generally subjected to heat treatment. It is typically supplied in the as-rolled or normalized condition.

7. Corrosion Resistance:

   • Like most carbon steels, A283 Grade C is susceptible to corrosion, and appropriate measures should be taken in corrosive environments.

Remember that specific requirements may vary depending on the manufacturer, and it's important to refer to the relevant ASTM standards and the documentation provided by the supplier for precise information regarding a particular batch of A283 Grade C steel.
