Description

In order to improve the mechanical properties of the parts, ETMA performs heat treatments with core and superficial hardening – tempering, carburizing, carbonitriding – and heat treatments with release of tension and hardness correction – tempering, annealing. All treatments are carried out in a controlled atmosphere, thereby ensuring a class of resistance up to 12.9 and high superficial hardness.
