20MnCr5 Gear Bright Round Steel Hot Rolled / Bright High Hardness
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.20MnCr5 Steel ,also refers to DIN 1.7147 steel as per European standard EN10084.As the representative steel of the Chromium-Manganese series of case hardening steel,it has high strength and toughness.
