Tribological investigations of hot-formning tools

Welding of high strength steel with pre-and post-heating techniques

SSAB is a global leader in value added, high strength steel. SSAB offers products developed in close cooperation with its customers to reach a stronger, lighter and more sustainable world.

Investigation of wear mechanisms

Olofsfors works in developing, manufacturing and sales within two different business areas, tracks for forestry machines and wear steel for construction machines. Most of the products are in hardened boron steel.

Fatigue testing of exchangeable rails

Industrial project with Rerail AB
- Fatigue testing of mount on rail

Rail to one hundred kilometres of railroad weighs about twelve thousand tons and the production of the same produces approximately twenty-four thousand tons of carbon dioxide. From a global perspective, the environmental benefits enormous.

Project Concept
To increase rail fatigue strength has a number of design changes been proposed. The project aims to clarify what impact the various changes has on fatigue resistance.
