About AST-Paulo
AST-Paulo provides commercial thermal processing, brazing and metal-finishing services. Its published heat-treatment range includes hardening, annealing, stress relief and other processes, with separate technical pages for vacuum heat treating and furnace brazing. The official site identifies Paulo as part of Aalberts and lists a corporate office plus processing locations in Missouri, Ohio and Tennessee. Vacuum heat treating uses controlled furnace conditions for supported alloys and applications; the company’s pages discuss process tracking and furnace-cycle documentation. Its brazing offering includes vacuum-furnace work, with the Cleveland division specifically identified for that process. The facilities in this listing are the disclosed U.S. sites. The listed Mexican site is excluded, and the process menu is not presented as a promise that every location performs every treatment.
