Performance Advantages:

  • Superior Formability: Excellent ductility allows complex shaping without cracking
  • Consistent Surface: Minimized imperfections (pits, scratches, roll marks) for coating readiness
  • Enhanced Weldability: Uniform chemical composition ensures stable welding performance
  • Dimensional Stability: Tight thickness control (±0.03mm) reduces machining allowances

Our DT4C steel undergoes strict quality control including spectrometric analysis and surface inspection systems. This guarantees chemical composition within JIS G3141 standards and surface roughness below 0.5μm Ra. The material's low carbon content (≤0.08%) contributes to its outstanding forming characteristics.

Industry Applications:

  • • Automotive body panels and structural components
  • • Electronic enclosures and chassis requiring EMC shielding
  • • Home appliance exteriors (refrigerators, washing machines)
  • • Precision stamping parts for industrial equipment

Backed by Shanxi Jurun Technology's decade-long expertise in steel processing and our 50,000-ton annual production capacity, we guarantee material traceability and on-time delivery. Our technical team provides application-specific guidance to optimize your material selection and reduce production costs.
