     The temperatures at which decalescence occurs vary with the amount of carbon in the steel, and are also higher for high-speed steel than for ordinary crucible steel.

   • 1964, Franklin D. Jones, Machine Shop Training Course - Volume 2, →ISBN, page 526:

     The decalescence point indicates the temperature at which a decided change In the Internal condition of steel takes place, and above which steel must be heated in order that it may be properly hardened by quenching.
