Applications: 
• Shafts, gears, cylinders and columns for industry 
mechanics in general. 
• Construction of mold 
• For compression molds, where the etching is not required. 
• Mechanical parts in general.

 

Heat treatment: 

Normalization: heating to 840 to 880 ° C, maintenance, furnace cooling to 600 ° C, then in air. 
Stress relieving: after rough heat to 500 ° C, 
maintenance raff. In oven to 400 ° C, then in air.
Hardening: preheating from 600 to 650 ° C austenitizing 
at 840 to 880 ° C, quenching in oil. 
Tempering: heating to 550 - 650 ° C and maintenance regime, again depending on the mechanical properties 
to be obtained.
