Some publications refer to this steel type as Thermo Mechanical Controlled Processed (TMCP) steels. Thermo mechanical rolling is a rolling process in which the final deformation is carried out in a particular temperature range leading to a material condition equivalent with certain properties which cannot be achieved or repeated by heat treatment alone. S460ML is also known as steel type 1.8838.
