The story

ESCO was founded in 1913 by Oregon businessman Charles (C.F.) Swigert as a local source of steel castings. The Electric Steel Foundry Company was founded on property once occupied by the 1905 Lewis and Clark Centennial Exposition.

During its first 30 years, ESCO was mainly a regional supplier of cast steel alloy products for the logging, construction, and pulp and paper industry throughout the Pacific Northwest. In the 1920s, the company expanded production to include cast steel alloy products. The ESCO trademark was first used in 1926 and eventually became the company's new name.

ESCO survived the Great Depression primarily as a jobbing foundry, making castings for sawmills, pulp and paper mills. In 1932, ESCO opened its first stainless steel industrial service center. During the 1940s, ESCO added new products to meet demand for supply valves, pump bodies, anchor chains and other components for warships and tanks. Postwar productions saw reforms to the company structure.

In 1983, ESCO bought Hyster Company, and then sold it in 1989 to NACCO Industries.

During the 1990s, ESCO expanded operations in the United States, the United Kingdom and Canada and entered a joint venture to manufacture products in China. The company also acquired Heflin Steel, producing wear liners and armor plate.

The company announced plans for an initial public offering in May 2011 that could raise as much as $175 million. The company canceled plans for an IPO in May 2013.

On December 28, 2012, Esco Corporation sold Turbine Technologies Group (Esco-TTG) to Consolidated Precision Products (CPP).

ESCO announced the acquisition of Texas-based Ulterra Drilling Technologies L.P. in August 2012 in a deal estimated at $325 million. In 2014, ESCO acquired another Texas-based company, Stabiltec Downhole Tools, LLC., further adding to the company's oil and gas portfolio.
