Right Answer:
- **15B25**: A low-carbon steel with approximately 0.15% carbon and 0.25% manganese. It is often used for structural applications and has good weldability.
- **10B21**: A low-carbon boron steel with about 0.10% carbon and 0.20% manganese. It is known for its good hardenability and is used in applications requiring high strength.
- **SCM-415**: A chromium-molybdenum alloy steel with approximately 0.40% carbon, 0.80% chromium, and 0.25% molybdenum. It offers good toughness and strength, commonly used in automotive and machinery components.
- **16MnCr5**: A low-alloy steel with about 0.16% carbon, 1.0% manganese, and 0.5% chromium. It is used for case-hardening applications, providing good wear resistance and toughness.
