high-strengthA high strength structural steel supplied in quenched and tempered condition. The steel is designed to provide excellent welding and bending properties and it offers substantial possibilities for savings in material costs, processing and handing. Due to its high strength, it enables design of lighter, more durable and efficient products and structures.
