Heat treatment


  • The surface hardness 58-62 RC decreasing gradually to prevent tread from spalling
  • The case obtained is uniform and continuous over the entire wheel tread and inner flanges. It meets requirements of AISE technical report #6.
  • The outer faces of the flanges are not hardened, maintening critical ductible properties to prevent flanges from breaking.
  • The bore, hub, webs, and outer faces of the flanges are not hardened leaving them tough and submissive. (Hardness 200-260 BHN)
Heat treatment

Our Hard and Deep Process combined with Monorail’s high carbon forged steel permits us to obtain a very strong surface hardness of 58-62 RC leaving the core tough and ductile. Our hardness pattern prevents flanges from breaking and also prevents tread from spalling. The Hard and Deep Process covers every aspect of the wheels heat treatment in order to obtain the ideal hardness pattern that ensures longer service life.
