There cannot be strengthening beyond about 100000 psi without significant loss in toughness (impact resistance) and ductility.
Large sections cannot be made with a martensite structure throughout, and thus are
not deep hardenable.
Rapid quench rates are necessary for full hardening in medium-carbon leads to shape
Distortion and cracking of heat-treated steels.
Plain-carbon steels have poor impact resistance at low temperatures. -Plain-carbon steels have poor corrosion resistance for engineering problems.
Plain-carbon steel oxidizes readily at elevated temperatures.
