Medium-Carbon Steels - an overview | ScienceDirect Topics

Martensite formed in medium and high-carbon steels (0.31.5 wt% C) is not stable at room temperature because interstitial carbon atoms can diffuse in the tetragonal martensite lattice at this temperature [5].Direct observations using the atom-probe show that the carbon atoms tend to segregate to defects and form small clusters at temperatures as low at 22 C [6].

Plain Carbon Steels: Classification and Limitations ...

Low carbon steels suffer from strain ageing, which does act as a method of strengthening, but as it raises the transition temperature of the steel, steels become brittle at room temperature. Low carbon steels also suffer from Luders band formation, which causes the surface to be rough and unpleasing, and which is undesirable.
