Designers of critical components are on a constant quest for materials that are lighter, stronger and capable of handling ever greater and more complex loads. They especially value high mechanical strength. Yet it is metal fatigue that causes the majority of premature failures in service. To combat this, Ovako has focused on developing clean steels in which the small inclusions that give rise to fatigue failure are closely controlled. Patrik Ölund, Head of Group R&D at Ovako explains how this is done.
Research and insights
Traditionally, steels were classified into four categories: tool steel, stainless steel, engineering steel and maraging steels. That mold was broken in 2017 with the launch of our Hybrid Steel – a new family of grades with an innovative alloying philosophy. The result is that the key properties of each category are available in one high-performance steel.
“Industry is facing a challenge from growing lead times for remelted steel”, says – Stefan Czeczor, Dip -ing. Manager Technical Customer Support. Stefan continues “in some cases, suppliers are quoting lead times of two years, with a minimum order quantity (MOQ) of 20 tonnes or more and with no flexibility to vary order quantity or dimensions.”
The carbon footprint of a material is just one aspect of a product’s environmental impact. How it is transported also influences the carbon footprint – and the impact can be surprising. Ted Lundström, our Head of Global Logistics, explains why.
