Quenching The Work






Category: CASE-HARDENING OR SURFACE-CARBURIZING

In some operations case-hardened work is quenched from the box by
dumping the whole contents into the quenching tank. It is common
practice to leave a sieve or wire basket to catch the work, allowing
the carburizing material to fall to the bottom of the tank where it
can be recovered later and used again as a part of a new mixture.
For best results, however, the steel is allowed to cool down slowly
in the box after which it is removed and hardened by heating and
quenching the same as carbon steel of the same grade. It has absorbed
sufficient carbon so that, in the outer portions at least, it is
a high-carbon steel.
