Exactatherm Ltd.

Exactatherm is a leading company for vacuum processing
in North America. It was the First to introduce ionitriding
surface treatment, vacuum oil quench heat treatments and
cryogenics to the Canadian metal working industry.
Ionitriding capacity, in three Toronto area plants,
is the largest in North America.
We pick up and deliver parts to our customers.

Processes include Ionitriding, PVD (Tin) Coating,
Cryogenic, Vacuum Heat Treating, Vacuum Annealing,
Age Hardening, Nitriding, Carburizing,
Neutral Hardening, Marquenching, Solution Treatment,
Tempering and Selective Treatment.

Quality Assurance
Exactatherm's QA Manual is in compliance with
MIL-I-45208, MIL-STD-45662 and AQAP-4.
Equipment at Exactatherm meets the following specifications:
Vacuum - MIL-H-6875, AMS-2750
Ionitriding - AMS-2759/8
Hardness Testing - ASTM-E18
For process control, all plants are equipped with a minimum
of two hardness testers capable of standard and superficial
testing and also one portable hardness tester for large sections.
The equipment is serviced every three months by an external
source and calibrated to national standards.
A metallographic laboratory is located at Head Office in
Mississauga equipped for metallographic examination,
micro-hardness testing and hardness profiles.

Certification
Exactatherm is qualified to perform
Certified Heat Treatment Services for aerospace, defence and
nuclear industry customers including,
AECL, Dehavilland, Devtek, General Electric, Indal Technology,
Litton Systems, McDonnell Douglas, Menasco Aerospace,
Pratt & Whitney, Rolls Royce (Canada) and Spar Areospace.
The QA Manual is available for inspection through the QA Manager.

Vacuum Heat Treating Metal parts are heated in a vacuum chamber. An applicable process temperature and cooling rate are selected to produce the desired transformation in the metal for wear resistance, toughness, strength and/or corrosion resistance. Typically, tools, plastics, moulds, metal castings, dies and machine parts are vacuum treated when surface quality must be maintained during service life.

Ionitriding Metal parts are heated in a vacuum chamber to a process temperature at which point process gases are introduced and electrically energised by the chamber wall to produce a glow discharge. Nitrogen is diffused into the metal parts surfaces and combines with certain elements to form hard nitrides. Typically, tools, form dies, forging dies, metal castings and plastics machine parts are ionitrided when surface wear resistance or corrosion resistance must be improved with minimum dimensional changes.

Cryogenics Parts are slowly cooled in a refrigeration vessel and held at a process temperature between minus 300-320 F, using liquid nitrogen as the refrigerant. Parts are slowly brought back to room temperature after the hold cycle is complete. Subsequent tempering is required on some materials to complete the process. Typically blades, broaches, fine blanking dies, carbide inserts, cutters, gauges and gun barrels benefit from the martensite and fine carbides formed during cryogenic treatment that improve stability, resistance to wear and chipping.

Stress Relieving Parts are heated in a furnace to a process temperature. The rate of heating and cooling and the process temperature are determined by the application requirements. Typically, welded fabrications, heavily machined/ground parts, drawn/cold worked parts and raw material are often stress relieved to remove residual stress that could eventually cause a part to distort, rupture or fail in some way.
