Title: Joseph C Jasper: Innovator in Steel Alloys
Introduction
Joseph C Jasper is a notable inventor based in Middletown, OH (US). He has made significant contributions to the field of metallurgy, particularly in the development of aluminized steel alloys. With a total of 4 patents to his name, Jasper's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents focuses on aluminized steel alloys containing chromium. This innovation allows steel alloys to be hot dip aluminized in a bath with up to 15% silicon, enhancing wettability through a bright preannealing process. The preannealing occurs in a box furnace with a substantially pure hydrogen atmosphere, ensuring that the surfaces of the preannealed steel are easily coated. The process requires a minimum soak of at least one hour at temperatures ranging from 675°C to 785°C (1250°F to 1450°F). It is crucial that the surfaces of the strip remain intact prior to aluminizing. During the aluminizing operation, the strip temperature does not need to exceed the bath temperature, as the strip has already undergone preannealing. The furnace atmosphere is maintained to prevent oxidation, typically using nitrogen, hydrogen, or a hydrogen-nitrogen mixture. This method results in improved wettability and significantly reduces uncoated spots on the steel surfaces.
