      Engineering considerations for material selection:<\/strong><\/p>

      When selecting S700MC, several key parameters must be considered:<\/strong><\/p>

      \u00b7 Forming Limit Diagram (FLD): To evaluate material performance during complex forming operations.
      \u00b7 Springback characteristics: High-strength steel exhibits 20\u201330% more springback than conventional steel.
      \u00b7 Die wear: Requires die materials with higher hardness.
      \u00b7 Welding process: Laser welding or resistance spot welding is recommended.<\/p>
