Brings Change The
whole field of heat treatments is continually evolving and
along with it come changes in the kinds of processes we use.
As our knowledge and expertise increases we are able to refine
what we do and find better and safer ways of doing things. A good
example of this is our move away from Cyanide Salt Baths.
Back in the 1970’s and early ‘80’s these
baths were very common. In fact Heat Treatments had no
less than ten molten salt baths in operation. Although
Salt Baths can be used to carburise (case harden) components
quickly, there are significant issues with using this process.
Top of the list is the fact that cyanide is a deadly poison
if used or stored incorrectly – ask any possum! In
addition cyanide salts will explode if water or moisture
is inadvertently introduced into the molten salt and, under
certain conditions, highly toxic hydrogen cyanide gas can
be released into the atmosphere. Today,
thanks to our awareness of the dangers of this process
and our increased knowledge and expertise in the area of
Sealed Quench Furnaces, we have been able to virtually
remove the need for Salt Baths.
Our Sealed Quench Furnaces are computer controlled and well suited
to batch work. Most importantly we are able to produce the same
quality results as a salt bath, without the environmental impact!
