Chemical composition of A283 Grade C steel plate

The chemical composition of the A283 Grade C steel plate is strictly controlled to ensure its excellent mechanical properties and processability. The main chemical components include:

Element content range (%)

Carbon (C) ≤0.24

Silicon (Si) ≤0.40 (plate thickness ≤40mm), 0.15-0.40 (plate thickness >40mm)

Manganese (Mn) ≤0.90

Sulfur (S) ≤0.040

Phosphorus (P) ≤0.035

Copper (Cu) ≤0.20

The control of these components makes A283 Grade C steel plate have good comprehensive mechanical properties.

A283 Grade C steel plate delivery status

The delivery status of A283 Grade C steel plate can be hot rolled, TMCP (controlled cooling and processing), normalizing and other heat treatment states. Among them, hot rolled and TMCP steel plates usually have better comprehensive mechanical properties. The heat treatment process may include annealing, normalizing and tempering, or, with the consent of the Purchaser, accelerated cooling by air blast or liquid quenching followed by tempering. The lower limit of tempering temperature is 675℃.
