20MnCr5 is a case-hardening steel with low carbon content but good hardenability reaching good wear resistance due to high surface hardness after hardening. The small grain size benefits in good ductility and fatigue strength. Suitable for gearboxes and axle gears.
All our forged 20MnCr5 material is melted in ultra-high power electric arc furnaces and then refined using advanced ladle metallurgy. Vacuum degassing and vacuum oxygen decarburization (VOD) processes assure optimum steel cleanliness,ESR that depends on clients needs,
