| When a low carbon steel is undergoing heat treatment for the purposes of casehardening, what is the process that distinguishes this procedure from other hardening methods? |
| A) After the steel is heated above its critical temperature, it is quenched in a carbon bath. |
| B) After the steel is heated above its critical temperature, it is quenched in cold water. |
| C) After the steel is heated above its critical temperature, it is allowed to cool slowly in air. |
| D) After the steel is heated above its melting temperature, it is quenched in a carbon bath. |
