Plain Carbon Steels: Classification and Limitations ...
The most important limitations of carbon steels are: 1. Low hardenability. 2. Low corrosion and oxidation resistance. 3. Major loss of hardness on stress-relieving tempering treatment. 4. Poor high temperature properties. The limitations of carbon steels are overcome by the use of alloy steels.
