TSH Benefits

  • Cost Effective Alternative Process  
    • Uses low cost TSH steels
      • 3-8 times less alloying elements (Mn, Cr, Ni, Mo)
      • Expensive alloy elements (Ni, Cr) are not specified
    • Replaces carburizing or conventional induction hardening for many alloy steel parts
      • TSH cycle times 1-5 minutes versus 8-20+ hours for carburizing
    • Lean and green process allowing individual gear traceability
  • Superior Metallurgy / Improved Durability
    • Produces fine-grain to ultra-fine grain martensitic structures within the surface hardened layer
    • Improves surface metallurgy by eliminating grain boundary oxidation or nonmartensitic surface layer associated with gas carburizing
    • Heat treated core structure (bainite and pearlite) resulting in a good combination of core ductility and strength.
    • Develops high magnitude of the desirable compressive surface residual stresses (600-800 Mpa)
    • Significantly improved static and dynamic properties
  • Simple, Repeatable and Robust Process
    • Parts are through heated or partial heated and then rapidly quenched 
    • Hardened depth is controlled by the steel’s hardenability
    • Limited steel hardenability allows the formation of well defined case depth and pattern when hardening complex-geometry parts
    • Uses low and medium induction hardening frequencies (1kHz to 15kHz)
      • Helps reduce equipment capital cost
      • Dramatically reduces probability of overheating edges, tips and corners
      • Improves overall repeatability and robustness and reduces process sensitivity
