Production of Stainless Steel: Part One :: Total Materia

These trials resulted in the first commercial AOD installation at Joslyn (now Slater Steel) in July l968. During the late 1950s, vacuum degassing processes (DH, RH, ASEA-SKF, Finkl VAD, etc.) were developed for carbon steel production, and led to the development of vacuum decarburization processes for stainless steels in the mid-1960s.
