Ovens

Ovens, also known as furnaces, are mostly used in the shop for heat treating parts. Heat treating changes the material properties of a part by redistributing its grain structure, making it harder or softer, tougher or more brittle, stronger or weaker. Heat treating is done by raising the temperature of the part above a critical temperature, then cooling it (precipitation) so that the grains crystallize (nucleate) into a distinct microstructure with different material states forming unique grain boundaries with differing material properties. Note that not all materials can be heat treated, so make sure you check first!

Barnstead Thermolyne 1400 Furnace

Also known as the "small oven", this furnace has a chamber size of approximately 5.00 x 4.25 x 6.00 in. (12.7 x 10.8 x 15.2 cm). It operates at temperatures from 100°C to 1100°C, although it should not be operated above 950°C for long periods of time.

Cress Electric Furnace C136

Also known as the "large oven", this oven is a little larger and can reach higher temperatures. The larger chamber is 10.50 x 13.00 x 8.00 in. (26.7 x 33.0 x 20.3 cm), and the temperature range of this furnace is 150°C to 1230°C, although it should not be operated above 1100°C for long periods of time.
