It’s hard to believe it all started in a garage. 

The Euclid Heat Treating Company was established in 1946 in a garage building with salt and open-fired furnaces. After decades of growth and expansion, the company is the most diversified commercial heat treater in northeast Ohio.

Over the years, Euclid Heat Treating has expanded to include endothermic atmosphere furnaces, induction hardening equipment, an array of vacuum furnaces, pit furnaces and nitriding equipment. It’s come a long way since the garage in 1946.

In 2008, the longtime MTI member relocated and expanded its offices to a neighboring building in Euclid, Ohio. The company was able to build a new production area for its growing Induction Division, including new induction power sources and a dual scanner. Euclid Heat Treating added other services at this time, including intensive quenching (IQ), eddy-current inspection, dimensional inspection and custom shipping.

With 55 employees, Euclid Heat Treating provides a wide range of services to the automotive, aerospace, military, mining, medical and heavy-equipment industries. These services include case hardening (carburizing, carbonitriding, nitriding, FNC), neutral hardening (quench and temper, normalizing), vacuum heat treating and induction heat treating.

Euclid Heat Treating prides itself on being a one-stop shop that can handle multiple heat treatments without having to ship parts to another company. For instance, the company can perform the initial quench and temper required on a pin, and then induction harden the OD to meet the specification. Euclid Heat Treating is also proud of its intensive-quenching furnace, mainly because it developed the process specifically for the benefit of customers.

One capability that is unique to Euclid Heat Treating is vacuum oil quenching. The company currently has one vacuum oil-quench furnace in operation, with a second in the process of being installed. While these furnaces can heat treat any oil hardening material, the unique combination of heating in vacuum and quenching in oil is ideal for material that needs an oil quench but also has an austenitizing temperature higher than what is typically run in an atmosphere furnace.

What really sets Euclid Heat Treating apart from other heat treaters, however, is its willingness to develop the best sequence of operations and heat-treating parameters for customers. For example, it might suggest at what point to stress relieve a part and when to harden it. Or Euclid Heat Treating may offer the option of induction hardening an area on a part rather than using no-carb masking paint. Some of these suggestions might save the customer time and/or money, and some might result in a better part.

In keeping with its tradition, Euclid Heat Treating is continually expanding and adding equipment. Two years ago, the company installed a 6-bar vacuum furnace. More recently, it purchased a rotary batch furnace and added warm oil quenching to one of its existing integral-batch furnaces. The latter has been valuable to customers with intricate parts that need to be oil quenched but with minimal distortion.

Looking ahead, Euclid Heat Treating plans on staying on top of technology with regard to the heat-treating needs of additively manufactured parts. The company also aims to make continuous workplace improvements so that it remains a place where employees are happy in their jobs.
