WP Winterboard Runners 4140
The WP Winterboards are modified and have a pair of runners similar to a DN iceboat on the rear. The runners act as the fin would on a windsurfing board. They make the Winterboard track straight and not spin out or slide sideways.
Alloy C4140 is an oil-hardening steel of relatively high hardenability. Its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. C4140 responds well to heat-treatment and is comparatively easily machined in the heat-treated condition. With a combination of such highly desirable properties as good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures.
The runner edge can be easily hardened to the point where it would need a belt sander to sharpen. It will hold a better edge than 1045 runners.
