• 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.
