Comprehensive Carbon Steel Grade Comparison & Equivalence Guide
At Huaxiao Metal, we provide carbon steel plates and sheets in accordance with all major international standards. Use the table below to find the equivalent grade for your specific project requirements.
| Steel Category | ASTM/AISI (US) | EN 10025 (EU) | JIS (Japan) | GB (China) | Key Characteristics & Applications |
| Mild / Low Carbon | A36 / 1010 | S235JR | SS400 | Q235B | Excellent weldability & formability. Used in general construction and bridges. |
| High-Strength Structural | A572 Gr.50 | S355JR | SM490 | Q345B | High yield strength with weight savings. Ideal for heavy machinery and skyscrapers. |
| Boiler & Pressure Vessel | A516 Gr.70 | P355GH | — | Q345R | High notch toughness. Specialized for pressure vessels, tanks, and boilers. |
| Premium Medium Carbon | 1045 | C45E | S45C | 45# | High strength and hardness. Suitable for shafts, gears, and mechanical components. |

Not sure which carbon steel grade is right for your project?
Standards like ASTM, DIN, BS, and AFNOR often overlap but have subtle differences in chemical composition.
Huaxiao Metal Technical Support: Our engineering team provides free material equivalency consulting. We help you analyze yield strength, tensile properties, and chemical requirements to ensure the steel you order performs perfectly in its end-use environment.
How to Choose the Right Carbon Steel Plate Grade: 4-Step Decision Framework
1. Define Your Structural Requirements
Is strength or formability the priority? What’s the minimum yield strength you need?
- Yield <250 MPa → A36 / Q235B / S235JR
- Yield 250–400 MPa → A572 Gr.50 / S355JR / Q345B
- Need pressure vessel cert → A516 Gr.70 / Q345R
2. Determine Surface & Tolerance Needs
Will appearance matter? Are tight dimensional tolerances required?
- Structural, hidden from view → Hot-Rolled (lower cost)
- Visible, precise dimensions → Cold-Rolled (smooth + tight tol)
- Painted/coated later → Hot-Rolled + blast cleaning
3. Check Fabrication Needs
Will you weld, bend, machine, or heat-treat this plate?
- Extensive welding → A36 / Q235B (low carbon)
- Machining → 1045 / C45E (medium carbon, heat-treatable)
- Springs, cutting edges → 1095 / 65Mn (high carbon)
4. Match to Your Market's Standard
Different regions require different certifications:
- North America → ASTM A36 / A572 / A516
- Europe / UK → EN 10025 S235 / S275 / S355
- Asia-Pacific → JIS SS400 / GB Q235 / Q345
- Cross-reference? → Free consulting available
