Nature Steel supplies 400 690TR TRIP Steel for Complex Stamping Structural Parts, a premium advanced high-strength steel (AHSS) specifically designed for complex stamped structural components. Utilizing the unique TRIP effect, it achieves a perfect combination of high strength and high toughness, completely resolving pain points such as easy cracking, poor forming accuracy, and insufficient safety performance during the stamping process of complex structural parts.
| Element | Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) |
| Content | 0.28 | ≤2.0 | ≤2.0 | ≤0.090 | ≤0.015 |
| Item | Yield Strength (Rp0.2, MPa) | Tensile Strength (Rm, MPa) | Elongation (A80mm, %) | n Value (10% ~ Uniform Elongation Section) |
| Value | 400~520 | ≥690 | ≥24 | ≥0.19 |
✅ Superior TRIP Effect: The microstructure consists of ferrite, bainite, and retained austenite. During deformation, the retained austenite transforms into martensite, ensuring excellent toughness and formability.
✅ Excellent Mechanical Properties: Yield strength 400~520MPa, tensile strength ≥690MPa, elongation ≥24%, achieving a balance between high strength and high toughness, perfectly suited for complex stamping requirements.
✅ High Stamping Adaptability: Possesses excellent strain hardening ability and deep drawing performance, enabling complex bending and stamping without cracking, reducing mold wear and production costs.
✅ Strict Quality Control: Certified by ISO 9001 and CE, 100% quality inspection before leaving the factory, precise control of chemical composition (carbon C: 0.28%, silicon/manganese Si/Mn: ≤2.0%), ensuring batch-to-batch performance stability.
✅ Customized solutions: We can customize the thickness, width, and surface treatment (uncoated, electro-galvanized) to meet your complex stamping needs, providing a one-stop supply service.
Q: What is the difference between ASTM A36 and Q235B?
A: Both are commonly used carbon structural steels with similar properties, but they follow different standards (ASTM vs. GB). A36 has a slightly higher yield strength and some differences in chemical composition. The specific choice depends on the project design requirements.
Q: Can you provide a material certificate?
A: Of course. Each shipment comes with an original manufacturer's material certificate (MTC) detailing the chemical composition and mechanical properties.
Q: What is the minimum order quantity?
A: We support small-batch purchases. Please consult our sales team for specific minimum order quantities.
