Leading heat treating companies in the U.S.

Posted by IndustryNet on Tuesday, March 27, 2018

100000210Heat_treatment_IGWHeat treating is a growing sector of the metal finishing industry. According to data gathered by IndustryNet on 454 companies employing heat treating processes, jobs have increased by 0.71 percent. An even more substantial jump in sales has been seen at 8.06 percent.

Heat treating is used to alter the characteristics of metal, such as hardness and workability. Hardening processes for metal have been utilized since 1400 B.C. The first iron foundries began in Cambria, U.K., around A.D. 1700.

Before the development of modern techniques, blacksmiths used heat to aid them in their trade. Softened metal was formed into the desired shape, then quickly cooled or quenched. This technique both increased the hardness and decreased the brittleness of the metal.

New developments

Though the underlying principles remain the same, the technologies of heat treatment have advanced. Multiple modern pathways have emerged. One option involves changes in the processes themselves. An example is a technique known as low-pressure vacuum carburizing in which reduced pressures are used to improve dimensional control on parts such as gears.

Another significant change is the continuing development of more environmentally favorable practices and equipment. Increased thermal efficiencies from methods such as electrical resistance and induction lower energy usage. Additional controls can lower the emissions of gases such as nitrogen dioxide.

The companies highlighted here illustrate how modern heat treating contributes to U.S. manufacturing. They serve a wide range of industries from aerospace to energy. Heat treatment may be executed on-site or within a facility.

Top companies by number of employees
