Niagara Specialty Metals is a manufacturer of tool steels, high-speed steels, martensitic stainless steels, powdered metals, and controlled-expansion alloys, including aerospace grades. Our company is built around producing customized orders of hard-to-obtain metals. We offer fast, factory-direct delivery of small or large quantities, custom-rolled and cut to your specifications. Niagara 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-sized orders and fast deliveries. The mill's flexible design allowed Niagara Specialty Metals to also hot-roll alloys for the aerospace, electronics, and other specialized industries.
