- Q: What are the different methods of surface peening for special steel?
- Some of the different methods of surface peening for special steel include shot peening, glass bead peening, and laser peening. Shot peening involves bombarding the surface of the steel with small spherical shots to create compressive stresses, which helps to increase the strength and durability of the material. Glass bead peening uses small glass beads instead of shots to achieve a similar effect. Laser peening, on the other hand, involves using high-energy laser pulses to generate shock waves on the surface of the steel, resulting in improved fatigue resistance and damage tolerance. Overall, these methods can enhance the performance and lifespan of special steel components.
- Q: How does special steel maintain its strength at different temperatures?
- Special steel maintains its strength at different temperatures due to its unique composition and specific manufacturing processes.
