STEEL BARS

CASE-HARDENING STEEL

Commonly used to enrich the surface carbon content of steel that case hardening provides. This is intended to produce a high-hardness, wear-resistant surface supported by a tenacious core.

Steel 18CrNiMo7-6

CHARACTERISTICS

Medium hardenable steel, which reaches high hardness after carburizing, ideal for parts that need mechanical resistance in the range of 80 to 120 Kgf/mm2 (800 to 1200 MPa or N/mm2) in the core.

APPLICATIONS

Used in the manufacture of gears, of larger or medium size, and pinion shafts for gearboxes.
