Field Heat Treating takes on many forms in terms of its application to materials, commonly referred to as Cooperheat or Cooperheating. It is defined as the in-field application of heat, to materials to intentionally alter their properties. The property changes can be physical and/or mechanical.
Cooperheat was one of the pioneering companies in the industry and subsequently became the generic and most recognizable name. Cooperheat as a company in North America no longer exists after it filed for Chapter 11. The Cooperheat brand was recently re-introduced by Stork a UK company, and the product line is unrecognizable to what previously existed in North America and most of the world.
