Is it necessary to water or oil quench the LCC material to obtain desired mechanical properties?

is any other heat treatment cycle by which we casn obtain desired mechanical properties in LCC material without quenching it or by just air cooling or forced air cooling.Is it necessary to water or oil quench the LCC material to obtain desired mechanical properties?
Sorry, what is LCC? Low carbon (?)





The only way to harden a steel alloy material by air cooling is if the alloy content is quite high - this is the reason for adding the alloys. If you don't have high alloy content, you MUST quench to harden the steel.





You're going to need a carbon content above 0.3% to see any improvement in properties from quenching.





Another heat treatment cycle on steel is case-hardening - this would improve surface hardness.
