European steel supplier Tata Steel has launched a range of stronger hot finished hollow sections for crane booms and other structures. The higher grade steel allows thinner sections that help reduce the weight of cranes and other off-highway equipment.
The Celsius 420 has a yield strength of 420 megapascals (MPa) and weight savings of up to 17 % compared with Tata Steel’s Celsius 355 grade products, the manufacturer said. Applications include lattice crane booms, cross bracings and cab structures.
Celsius 420 hollow sections, with higher yield strength, can be used as a thinner section, helping equipment manufacturers meet targets for emissions and fuel consumption through weight reduction, the manufacturer said. The steel has a lower carbon equivalent value (CEV) of 0.45, putting it in the "good" category for welding.
Henrik Adam, Tata Steel chief commercial officer in Europe, said, “While our Celsius range is already very well established in the structural hollow sections market, we know our customers are always looking for new materials with enhanced properties. This is why we focus so much on innovation to develop next-generation products. We’re bringing to market an entirely new range of hot-finished hollow structural sections that we believe is in a class of its own. Celsius 420 guarantees proven performance and quality assurance, offering customers design freedom and manufacturing confidence.”
Kevin Edgar, Tata Steel head of marketing, engineering sectors for European operations, adds, “Being a hot-finished structural hollow section product with added strength, Celsius 420 offers equipment makers big advantages through lower material costs, good welding and improved performance thanks to the high degree of uniformity in wall thickness. Customers can reduce the weight of the material they use for equivalent performance, which gives further benefits in terms of weight savings.”
