What is the chemical composition of 3mm carbon steel plate ST52

The chemical composition of a 3mm carbon steel plate ST52 can vary depending on the specific standards and specifications followed. However, as a general guideline, the typical chemical composition of ST52 carbon steel may include:

- Carbon (C): 0.20% - 0.24%
- Silicon (Si): 0.15% - 0.50%
- Manganese (Mn): 1.60% - 1.90%
- Phosphorus (P): ≤ 0.040%
- Sulfur (S): ≤ 0.040%
- Chromium (Cr): ≤ 0.30%
- Nickel (Ni): ≤ 0.30%
- Copper (Cu): ≤ 0.30%

These percentages represent approximate ranges and can vary based on different sources and manufacturing processes. It is essential to refer to the specific material standard or mill certification for precise composition information.

Please note that the mentioned composition refers to the general range for ST52 carbon steel; however, variations may exist based on specific requirements or regional standards.
