C Si Mn Cr Mo P S
4140 0.38~0.43 0.15~0.35 0.75~1.00 0.80~1.10 0.15~0.25 ≤0.035 ≤0.040

Advanced Heat Treatment: Optimizing Alloy Properties

Converting raw materials into high-performance alloys requires a meticulous heat treatment process that enhances the steel’s microstructure to maximize its capabilities.
  • Annealing:
This controlled heating and gradual cooling process alleviates internal stresses, resulting in steel that is both ductile and free of stress.
  • Quenching:
Rapid cooling ‘traps’ hardness, forming a martensitic structure.
  • Tempering:
The concluding step refines the steel’s toughness by minimizing brittleness.
  • Yield Strength:
An Essential Measure of Material Durability
Yield strength measures the steel’s resistance to deformation. It marks the point where the material shifts from elastic to plastic deformation, which is crucial for applications requiring high structural integrity.
  • Testing Methods:
State-of-the-art equipment is used to test the steel’s limits and ensure precise yield strength measurements.
