Ruukki has developed special steels for applications in which tubes or hollow sections are required.
Raex 400 wear-resistant steel's martensitic, homogenous microstructure throughout the tube wall helps to provide long life for wearing parts. The cold-formed steel tube is nearly three times harder than regular S355 standard steel.
Optim 700 Plus MH structural hollow sections are high-strength but lightweight to contribute to fuel savings through lighter vehicle structures. Their cold-forming properties and impact toughness make them suitable for applications such as mobile machines, materials handling equipment, and cranes.
