Rautaruukki Oyj : Ruukki's high strength and wear-resistant special steels now
in tubes and hollow section form
Rautaruukki Corporation Press Release 19 April 2013 at 1.30pm EEST
Ruukki's special steels have been bringing benefits to equipment manufacturers
for years already in plate and strip form. Now Ruukki has developed both
special steels for applications where either tubes or hollow sections are
required. Raex wear-resistant steel enables a longer lifetime for wearing
parts. Optim high-strength steel brings fuel savings through lighter vehicle
Raex 400 tube is the hardest cold-formed steel tube in the world
Raex 400 tube is nearly three times harder than regular S355 standard steel.
Its martensitic, homogenous microstructure throughout the tube wall guarantees
a long lifetime in abrasive materials pumping applications.
Raex 400 tube has been designed for the cost-efficient transport of wet
concrete and other semi-fluid liquids and wear materials. It significantly
improves the performance of pumping or dredging equipment and extends its
service life beyond normal standards. The steel tubes can also be used for the
wearing parts of mining machinery, excavation and dredging equipment, as well
as in forestry machinery and equipment.
Optim 700 Plus MH hollow sections
Use of Ruukki's extra high-strength Optim 700 Plus MH structural hollow
sections enable lightweight lifting and transportation equipment without
compromising on properties. Lightness brings cost savings in fuel costs and
results in higher payload capacity. Optim 700 Plus MH structural hollow
sections clearly exceed standard requirements and the properties of other
similar steels on the market.
Optim 700 Plus MH structural hollow sections have improved cold-forming
properties and impact toughness, which makes them ideal for applications such
as mobile machines, materials handling equipment and cranes, where high
strength combined with excellent usability is required. Product engineering
usability is excellent and the product has improved welding properties.
Ruukki is committed to continuously improving the energy efficiency of its
steel production. The company ranks among the most energy-efficient in the
world in iron-making and uses nearly the minimum amount of coking coal
possible using current technology. Strong R&D capability enables Ruukki to
develop high quality products in response to the market and various
