Materials
AMS – high-manganese steel is distinguished by its excellent strength and wear resistance and is therefore used mainly as basic material for crossings and switches made of grooved rails.
This steel with 13% manganese content forms a particularly wear resistant surface and is, for this reason, used for highest axle loads.
The castings are manufactured at the foundry of the VAE affiliate JEZ.
The patented flash-butt welding process of VAE permits the connection of AMS with common rail steel and therefore it can be welded into the CWR track.
HSH (Head Special Hardened)
Use of optimum materials, particularly for turnout components subjected to highest loads.
Head-hardening of the rail, directly from the rolling heat
Milling of the tongue rail
HSH (Head Special Hardened)
Material used in switch devices subjected to high loads as well as in running rails to reduce wear.
The fine perlite structure with high hardness values in the inside of the rail head is of special importance because part of the rail head is machined.
