Application : Automobile Industry,
Pharmaceutical / Chemical Industry
SAE 8620 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. This combination of properties provides wear resistance and
fatigue strength at the surface, and impact strength in the core. Presence
of Nickel and molybdenum increases ductility and toughness and resistance to
corrosion.

Applications :
Gears of all kind, camshafts, universal joints, driving pinions, link
components, axles and arbours. All these components must resist wear and
fatigue, have inherent toughness, and still be machinable. Request Callback
