Swebor Stål

Swebor Stål is a specialist steel company on the world market, their speciality is heat-treating thin boron steel. They provide heat-treated Sheet, Grouser Bars, Cutting Edges and boron steel Profiles to customers worldwide.

The heat-treated boron steel from Swebor is a carbon-manganese grade with chromium. The addition of boron gives the steel its unique combination of hardness, strength and weldability after heat treating. In the hot-rolled state, boron steel is softer and can be machined or formed without soft annealing.

Boron steel has several advantages compared to common tempering steels. Boron steel can be hardened and the carbon content balanced so that subsequent tempering is not necessary. The new boron steel also has special advantages over other heat treatment steels. Above all, better strength relative to hardness, but also better weldability, fatigue strength and wear resistance. They deliver heat-treated profiles and sheet in lengths up to 8 metres.
