... of minimizing scaling and/or surface decarburization. An advantage of the T steels over the M steels is that they are less sensitive to decarburization. In controlled-atmosphere furnaces, the M steels will decarburize even in a reducing CO atmosphere. For example, in an 11% CO atmosphere at 1200 °C (2200 °F...
