Our History

History of Niagara Specialty MetalsNiagara Specialty Metals was founded in 1982 by J. Barry Hemphill and Louis Valery. They established a steel mill to serve the tool and stainless steel markets, focusing on custom size orders and fast deliveries. The mill’s flexible design allowed Niagara Specialty Metals to also hot roll alloys for the aerospace, electronic, and other specialized industries.

Over the years, Niagara Specialty Metals has evolved beyond just rolling metals. We have added specialized equipment to process sheets and plates after rolling them to gauge. Notably, we possess some of the finest roller levelers in the market for flattening difficult or brittle alloys such as Titanium and Molybdenum. Additionally, we have extensive cutting and machining capabilities.

The workforce at Niagara Specialty Metals is the cornerstone of the company’s success, with many employees having been with the company for 25 years or more. Their dedication and continuous efforts to improve processes and customer service are key reasons why so many companies trust Niagara Specialty Metals with their valuable materials.

In 2004, J. Barry Hemphill generously transitioned ownership of the company to its employees, making Niagara Specialty Metals a 100 percent ESOP (Employee Stock Ownership Plan) owned company. This move has further cemented the company’s commitment to its employees and its mission of excellence in the specialty metals industry.
