Q235 steel characteristics
steel Product Introduction
Chemical composition
The main chemical elements of Q235 steel include:
Carbon (C)
Silicon (Si)
Manganese (Mn)
Phosphorus (P)
Sulfur (S)
Below is the chemical composition table of Q235 steel, providing a clearer understanding of the main elements:
| Steel Grade | Standard Steel Grade | C % (≤) | Si % (≤) | Mn (≤) | P (≤) | S (≤) |
| Q235 | Q235A | 0.22 | 0.35 | 1.4 | 0.045 | 0.05 |
| Q235B | 0.2 | 0.35 | 1.4 | 0.045 | 0.045 | |
| Q235C | 0.17 | 0.35 | 1.4 | 0.04 | 0.04 | |
| Q235D | 0.17 | 0.35 | 1.4 | 0.035 | 0.035 | |
| Standard Steel Grade: A<B<C<D | ||||||
Note that steel grade standards are typically classified in the order from A to D, with each grade having specific requirements for chemical composition and mechanical properties.
However, it is important to remember that the chemical composition of Q235 steel plate may vary depending on the standards and regulations of each country. Adhering to regulations and standards related to the chemical composition of steel is crucial to ensure the quality and consistency of the product.
Mechanical Properties
These mechanical properties include yield strength, tensile strength, and elongation, which are important factors in measuring the steel's ability to withstand forces and deformation. However, the specific values of these properties may vary depending on production conditions and specific regulations of each country.
| Steel Grade | Yield Strength | Tensile Strength | Elongation % |
| Q235 | 235 Mpa | 370-500 Mpa | 26 |
| Test Sample: Steel Plate Q235, (Mpa=N/mm2) | |||
