SSAB Boron Tube 24

General Product Description

SSAB Boron Tube 24 is a structural hollow section for hardening. It offers good workshop properties in delivery condition. The degree of hardness and toughness that can be achieved after heat-treatment will provide the final products with wear- and shock resistance properties that assure longer lifetime.

Dimension Range

SSAB Boron Tube 24 is available at circular.
