Typical applications

Machinery elements with good resistance. Hydraulic blocks, mould and portable moulds.
Good temper. It can be used for temperate induction pieces whichh require superficial hardness of 55 HRC.


Soldering steel to appropriate soldering process. It requires a controlled preheating and cooling, considering warm reduction tensions treatments after soldering. 200-250ºC preheating is recommended and long-term cooling mode.


Deficient. Shaping can be improved applying softening or globular annealing.
It's recommended to shape always in a warm way.


Specify an annealing or stabilized treatment after the oxycut to eliminate the resulting superficial hardness.
