Cost Reduction In Heat Treatment

  • Several benefits accrued by the use of this coating are: ESPON-AS protects metals and alloys against oxidation and decarburisation during heat treatment.
  • ESPON-AS coated tools and components can be heat treated in air using a box-type or bogie hearth; electric, gas or oil fired furnace. 
  • ESPON-AS eliminates need of salt bath or expensive controlled-atmosphere equipment in many cases. 
  • Considerable savings in capital investment and operating costs. 
  • Due to prevention of decarburisation, uniform surface hardness is achieved. 
  • Ability to salvage the rejected components by re-heat treatment. \
  • Elimination or minimization of post heat treatment operations like grinding, shot blasting, acid pickling, etc. 
  • ESPON-AS is suitable for working temperatures upto 1200°C.
  • ESPON-AS is non-flammable and non-hazardous. No toxic or volatile materials are expelled from the coating during mixing or heat-treating the coated components.
  • A number of leading heat treatment shops have confirmed the benefits of ESPON-AS.
