Isothermal hardening salt series

(Isotherma hardening salt, Stepped quenching salt)

 

 

The technique and the salt are R&D by Gnail.

Working temperature: 
                   150~400°C (Low temperature isothermal hardening salt )
                   500~700°C (middle temperature isothermal hardening salt )
24 working hours aging ratio :  No

Middle temperature isothermal hardening salt can be used for oxideproof tempering and stepping quenching salt at 500~700°C or oxideproof tempering in harden die steel such as Cr12MoV, H13. It also can be used in solid solution process of aluminum alloy.  The liquid salt is very stable.

Low temperature isothermal hardening salt has a very good fluid so as to cool the workpiece uniformly, It is good for all steel isothermal hardening, stepped quenching, low temperature temper. The liquid salt is very stable and never aging.

       *Low temperature isothermal hardening salt is unsuitable for aluminum and aluminum alloy
