The Bethlehem Steel Corporation was the number two steel producer in the United States between 1916 and 1984. For a time it was also the largest shipbuilding firm in the world. The records of the Bethlehem Steel Corporation (parent company) are a series of fragments, lacking the complete runs of corporate and executive documents that normally comprise a business archive, and largely consist of fragmentary corporate records and files from executive officers.

The Heintz Manufacturing Company was originally organized by Leo Heintz in Philadelphia in 1921. The firm initially manufactured all-steel pre-assembled truck bodies but later expanded to produce a wide range of pressed sheet-metal products. The records primarily focus on the company’s contractual obligations with the US Navy during World War II; employee retirement and pension plans; descriptions of various welding processes and tools, and material related to the licensing of cold welding under the trademark, "Koldweld."

The Lukens Steel Company was a medium-sized, non-integrated steel company and one of the top three producers of steel plates in the United States. Lukens operated continuously at its Coatesville, Pennsylvania, site since 1810 and was one of the few successful survivors of the many nineteenth-century iron works that once dotted southeastern Pennsylvania. This collection of Lukens Steel Company records consists of corporate records, mostly from the Secretary's Office. The records are comprised of seven series: Shareholders' meeting agendas; Stockholder lists; Proxies for annual meetings; Board and committee meeting agendas; Financial statements; Secretary's correspondence; and Counsel's correspondence.
