Ferobide has been successfully used on tunnel boring machines (TBMs) to protect areas of the cutterhead in the Swedish Hallandsåsen tunnel project. It presents a long lasting and weldable option to conventional hardened steels and hardfacing rods, saving significant time on maintenance.
Ferobide was the material on the forefront of Sweden’s most challenging railway project – successful boring through the “impenetrable Hallandsåsen mountain” to construct two parallel tunnels with a unit length of nearly 5,500 metres and an interior diameter of about 9 metres. The tunnels are the country’s most important railway infrastructure project in 40 years. Capacity will increase from 4 to 24 trains per day, travel time between Malmö and Gothenburg will be shortened and the load capacity of freight trains will double.
None of this would be possible without Ferobide.

- Ferobide gives life increase of 6-7 times – comparing to 500HB hardened steel
- At 5 months 500HB hardened steel is completely worn out, while Ferobide has 85{b31dfa9a7c8099c314e960b46e483f159faba86f4e59565e93b438ccc25543d8} wear life left
- Ferobide exhibits work-life of 26 months
- Ferobide reduced downtime significantly and speeded up the completion of the project
What is Ferobide exactly?
Ferobide is a weldable tungsten carbide composite material, which combines high levels of wear resistance with the ease and reliability of a weldable material.
Key Features:
- Weldable
- Resistance to sliding abrasion comparable to tungsten carbide
- Higher abrasive wear resistance than any other weldable material
When compared to other common wear resistant materials in sliding abrasion, Ferobide is:
- 15 times better than 500 HB hardened steels,
- 8-10 times better than chromium carbide plates,
- 6 times better than cast white iron,
- 4 times better than 97{b31dfa9a7c8099c314e960b46e483f159faba86f4e59565e93b438ccc25543d8} alumina.
