Castelli Pietro has several heat treatment plants, located in different production departments.
In TT1 department, 3 induction hardening plants are installed.
In TT2 department, 2 continuous quench hardening and tempering lines are installed.
In the last two years, both lines have been electrically rewired and upgraded to the requirements of CQI-9 standard.
All the machines use quenching oils - constantly regenerated - supplied by a leading company in the sector, which every six months verifies that the properties of the oil comply with the specifications.
Both lines are in a controlled atmosphere.
In the month of June 2020, a new endogas generator was installed in the department, in line with the current standards in terms of both safety and treatment.
