Material and Chemical Composition
The material of the steel strips is mainly carbon structural steel and low-alloy high-strength structural steel. In some scenarios, special materials such as stainless steel and heat-resistant steel will be used. The chemical composition of different grades strictly follows the corresponding standards. The core components and characteristics are as follows:
| Material Grade | C | Si | Mn | P | S |
| Q235 | ≤0.22 | ≤0.35 | ≤1.40 | ≤0.045 | ≤0.050 |
| Q355 | ≤0.20 | ≤0.55 | ≤1.60 | ≤0.035 | ≤0.035 |
| Q460 | ≤0.20 | ≤0.60 | ≤1.80 | ≤0.035 | ≤0.035 |
Mechanical Properties
The mechanical properties of the steel strip are determined by the material, processing method (hot rolling / cold rolling), and heat treatment method. The key indicators and general application scope are as follows:
| Performance Metrics | Q235B | S235JR | A36 | SS400 |
| Yield Strength(ReL) | ≥ 235 MPa | ≥ 235 MPa | ≥ 250 MPa | ≥ 245 MPa |
| Tensile Strength(Rm) | 370 - 500 MPa | 360 - 510 MPa | 400 - 550 MPa | 400 - 510 MPa |
| Elongation(A) | ≥ 26% | ≥ 26% | ≥ 20% | ≥ 21% |
| HB(HB) | ≈ 120 - 150 | ≈ 120 - 150 | ≈ 120 - 150 | ≈ 120 - 150 |
| Impact Work (Akv) | ≥ 27 J (20℃) | ≥ 27 J (20℃) | ≥ 27 J (20℃) | ≥ 27 J (20℃) |
