1.7131 (SAE 5115)
Processing & galvanising
Mechanism for closing a bus, train or tram door.
- Wear-resistant steel alloy
- Smooth surface, also on cast gearing
- Savings in material costs and processing costs
- Casting of the gearing and square axle hole without post-processing
Advantage of the CIREX casting process
No processing required for the gearing: the entire profile of the teeth can be cast. Therefore, only a broaching process of the pre-cast square assembly hole is required. This achieves significant cost savings. Component is delivered ready to be built in, including (black) galvinising.
