Q: What is the hardness range of DC01?
A: There is no specific hardness specification for ordinary DC01. Its high-strength version, DC01-C590, has a hardness of 160-210 HB.
Q: What are the cupping value requirements for DC01?
A: The cupping value of DC01-C590 is ≥7.5mm. Ordinary DC01 also has good formability and excellent cupping value performance.
Q: How is the fatigue resistance of DC01?
A: Its high-strength version, DC01-C590, has a fatigue resistance (10⁷ cycles of stress) of 320MPa. Ordinary DC01 can also meet the fatigue resistance requirements of general components.
Q: What are the requirements for hydrogen embrittlement susceptibility of DC01?
A: The EN 10130:2020 standard has added hydrogen embrittlement susceptibility testing requirements, strengthening the safety of material use.
Q: How is the aging stability of DC01?
A: The DC01-C390 has a stable lifespan of up to three months, making it suitable for mass production scheduling. If used beyond this period, its mechanical properties need to be retested.
