General specifications*

C 0,37-0,43. Mn 0,60-0,90. Si 0,15-0,40. P ≤ 0,025. S ≤ 0,035. Cr 0,85-1,15. Mo 0,15/0,26.
Rm900/1100 N/mm². ReH700 N/mm². A 10 %. Dureza Brinell300/344Hb.

Typical applications

Typically used for parts, treated, requiring a higher hardness. They are achieved by oil quenching until 45/58HRC and 160/200Kg/m. Some applications are for automotive industry and aeronautics: gear assembly, connecting rods, pieces that require induction hardening to get high requests.

Soldering/Folding

Soldering steel to appropriate soldering process. It requires a controlled preheating and cooling, considering warm reduction tensions treatments after soldering.

Mechanization

Good. If accurate oxyfuel stabilizer or annealed after the torch cutting of parts.
