Choosing the right heat treating furnace for your application can be a tricky process, as you are inundated with a seemingly unending parade of heat treating categories, feature sets and so on. We’re here to make the decision just a little bit simpler, with a brief explanation of the two types of Cress furnaces.
When it comes to Cress heat treating furnaces, there are two main types available for sale:
- Heat treating furnaces (benchtop heat treat furnaces and mid-size heat treat furnaces)
- Draw furnaces (benchtop draw/tempering furnaces and mid-size draw/tempering furnaces)
EPS carries the entire line of Cress Heat Treat Furnaces, including lab furnaces, cress mid-size dual chamber, medium and large production furnaces, and even a 15.75 cu. ft. drop bottom quench furnace or 27 cu. ft. drop bottom quench furnace for the solution heat treatment of aluminum.
Heat treating furnaces operate using higher heat output than draw furnaces and are used to harden, strengthen and reduce residual stress of materials. Furnaces in this category generally have a temperature max of around 2250 degrees Fahrenheit, and are suitable for most general use in the shop or lab.
Draw furnaces, also known as tempering furnaces, on the other hand, are used for lower-temperature applications including annealing, tempering and stress relieving. Normal maximum temperature for a draw furnace is closer to 1250 degrees Fahrenheit. Draw furnaces are most often used to heat a quench hardened material to below its transformation range in order to reduce brittleness and relieve internal stress.
Each type of furnace comes in a range of sizes, from small lab furnaces to large capacity production furnaces.
