Escalator pressure roller Mitsubishi 60x55x6202 handrail belt roller Escalator Pole Wheel Tug Roller

Mitsubishi Escalator pressure roller wheel 60x55x6202 has two kinds of nylon core and aluminum core. The hardness of the main 65Mn steel plate on the market is generally below HRC20 and the hardness of the 65 manganese steel plate after heat treatment can reach HRC60 or more. And the hardness after quenching is generally around HRC62. When made into various workpieces (baffles, gaskets, spring plates.... The hardness will generally be between HRC40-55.

The most important feature of high manganese steel is that under strong impact and extrusion conditions, work hardening occurs rapidly on the surface, so that the hardened layer has good wear resistance while maintaining good toughness and plasticity of austenite at the core. The typical Mn17 wear-resistant high manganese steel is based on Mn13 steel to increase the amount of manganese, improve the stability of austenite, prevent the precipitation of carbides, and then improve the strength and plasticity of steel, improve the work hardening ability and wear resistance of steel.
