CHARACTERISTIC |
APPLICATION |
| 5919 is a low carbon low alloy steel. With tensile strength 780-1,060 N/mm2 (after heat treatment). Available for case hardening by carburizing (surface hardening 58-60 HRC, core hardness 25-32 HRC) | Structural parts requiring good wear resistant surface and a very tough core e.g. stems, shafts, axles, connecting rods, crank shafts, pinion gears and machinery parts. |
