Celsius 420 was developed for applications where structural performance at a reduced weight is required and represents innovative advances in steel manufacturing.
Offering a high yield strength of 420 megapascals and weight savings of up to 17% compared with Tata Steel’s Celsius 355 products, Celsius 420 is designed for use in mining equipment including in structural components, vehicle axles and cab systems.
Reducing the weight of the vehicles used is a constant focus for equipment manufacturers, who are under pressure to meet strict emissions and fuel consumption targets.
The use of Celsius 420 hollow sections helps them meet these aims, due to the fact it can be used as a thinner section, with a higher yield strength, according to the company.
“Celsius 420’s manufacturing process ensures that the product has no weaknesses around its whole perimeter and weld line,” it said.
“This enables the product to be used in more demanding applications. Combined with the steel’s lower carbon equivalent value (CEV) of 0.45, compared to the 0.5 product standard of EN 10210, this product is also easier to weld and fabricate. Not only is steel with a lower CEV better for welding, but it requires no additional heat treatment, making the steel more cost-effective to process.
“The steel’s strong weldability – unique in high-strength tube products – means high-strength components can be produced without changing standard weld procedures. In addition, tighter radii can be maintained on the corner profiles of square and rectangular sections to ensure a smaller surface area, reducing weight and risk of fracture.”
Tata Steel works with some of the world’s largest original equipment manufacturers in the earthmoving, mining, and material handling sectors.
Tata Steel Europe chief commercial officer Henrik Adam 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.”
