BORON steel is in the same group as HSS steel.

The dark gray components are manufactured in Boron steel. The gray sections in the illustrations are High Strength Steel (HSS) with a tensile strength above 340 MPa and must therefore be treated with extra care during repair.

Boron steel has a very high tensile strength, 1150 MPa, and a very high yield point, 1550 MPa.

When replacing Boron steel components, the welds cannot be drilled. Grind or plasma cut instead.

Boron steel has good tolerance for welding.

It is not possible to galvanize Boron steel during manufacture. These components must be rust-proofed extra thoroughly.
