Hardness relationship between crane wheel forgings and rails

There is a certain relationship between the hardness of the track and the wheel forgings. The hardness of the blindly strength wheel reaches HRC40 or more, or even higher, will produce a lot of wear on the track. In the friction between the wheel forgings and the track, we hope that the track will have a longer life than the wheel forgings. This is according to the actual wear situation, because there are a lot of tracks on the market now are Q235, and ordinary steel plate is a model, and 55Q is better, but the price is also expensive, now there are 42CrMo, 65Mn material crane wheel, especially 65Mn material crane wheel cost performance is higher.

This you have to see the actual wear, because there are a lot of tracks on the market now are Q235, and ordinary steel plate is a model, and is 55Q is better, but the price is expensive, now there are 42CrMo, 65Mn material crane wheel, especially 65Mn material crane wheel cost performance is higher. Crane wheel forgings are generally no. 45 steel after heat treatment and no. 55 just quenching and tempering heating treatment, there is a lower grade of iron wheel.

If the hardness, depends on how you match, good wheel forgings with ordinary rail, if there is gnawing rail, the track must grind but the wheel, if it is high quality configuration, gnawing rail, should be said to be lose-lose. If not gnaw track, ordinary enough for you to use for several years.
