In 1926 Albert Diehl founded the Diehl Steel Company in Cincinnati, Ohio to service the tool steel needs of one of the countries largest machine tool hubs. Coming from a tool and die background, Mr. Diehl knew the importance of fast, efficient service and high quality products. After 85 years in business, that tradition of service continues today.
