Material Grade for Monorail's Forged Steel Wheels

  The material selected for the making of our wheels is a high-carbon steel.

  AISI 1070 Forged Steel, made from vacuum degassed ingots (E.F., FG., V.D. STEEL), provides exceptional strength while resisting to wear.

  The higher carbon content permits better hardenability.

Heat Treatment

  Throughout research, development and many years of experience, Monorail has developed the Hard and Deep Process (HDP).

  Our team aims to achieve a prime combination of strength, toughness and wear in each wheel we manufacture, to ensure customers receive a

  superior quality product. 


  Our unique heat treatment procedure, HDP, offers maximum hardness, a deeper hardness penetration for extra resistance to wear, and a longer 

  service life where heavy loads and severe service conditions are encountered.  


  Wheels are quenched to a hardness higher than 62 Rockwell C in order to obtain a hard martensitic structure throughout the rim and furnace

  tempered to detent stresses and adjust final hardness upon the service requirements of our customers' various applications.  

  HDP 58-62 RC,     HDP 52-55 RC,     HDP 48-52 RC (450-500 BHN)

  Wheels are also manufactured in accordance with ASTM A504 Class A, Class B, or Class C (321-363 BHN) for chemistry and hardness. 

  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.


When it comes to machining, Monorail is in a class of its own.

    • Monorail is equipped with the latest technology in CNC machines which enables us to meet the most stringent customer specifications by producing completely finished high quality wheels.
    • Our high-tech environment of CNC machines enables us to meet customer's designs and specifications to perfection with high precision, tight  tolerances, wheel concentricity, and superior surface finishing all over.  
    • With our CNC machines, all series of wheels are produced identically and are absolutely concentric. Therefore, our product avoids any vibration which decelerates the wear of wheels. 

Quality Assurance


  Monorail Quality Steel Wheels are achieved through continuous improvement programs, covering each phase of the business to meet and

  surpass customer requirements.
