Tools that are heat treated in molten salt baths are heated up much more rapidly than by convection or radiation, thereby heat treating times are significantly shortened. The molten salt provides a ready source of heat and maintains the rate of heating necessary to reach equilibrium with the rate of heat absorption.

Massachusetts Institute of Technology has published a new study that shows what happens when crystalline grains in metals reform at nanometer scales, improving metal properties. This includes recrystallization, in which the metal is deformed and heated.

Can-Eng Furnaces International Ltd, Canada, has been awarded a contract to deliver a high-capacity mesh belt heat treatment furnace line to a commercial heat treater in the Midwest U.S.
