The crossing as one of the most important components in a turnout is installed at its end. Due to its role in guiding the train to the diverging line, it is also called as the core of a turnout.

The crossing should be produced from high manganese austenitic steel (Hadfield) according to UIC866-O or EN 15689 standard.

Hadfield steels have manganese alloy elements (some twelve percent by weight) and carbon (some one percent by weight) with small amounts of other elements such as molybdenum, nickel, silicon, etc. They are of an austenite structure (a type of iron crystal structure that is often stable at high temperatures) during the casting operations, while in shape changing processes, they turn into martensite (a common crystal structure in heat treated steels with a very high hardness and strength). Hadfield steels have moderate strength and suitable flexibility, being used in various industries such as rail industries, heavy road construction machinery, cement industries, etc.

The weight of this piece is about 1.3 tons, which is produced by casting method.

Production steps of the Crossing:

1- Design

2-Casting and heat treatment

3- Machining

4- Connecting the antennas to the cast Crossing by welding
