The extra-high tough steel for structural wear parts
Hardox® HiTuf is an abrasion-resistant plate with guaranteed impact toughness. With a nominal hardness of 350 HBW, it's a good choice for structural wear parts like thick cutting edges, demolition tools and rippers.
Shredders made of Hardox® HiTuf a smashing success
The Australian company Pacific Shredder designs and builds steel shredding machines that can shred a car into scrap in seconds. They rely on Hardox® HiTuf to keep their shredders working when those made of softer material fail.
Pacific Shredder, located in Newcastle, New South Wales, was looking for a steel that was stronger and lasted longer. Normal steel is prone to cracking and wear, and has to be replaced often.

“Steel recycling is all about dollar-cost per tonne," says Beentjes. “The cost of scrap and the price for recycled steel are pretty much fixed, so one of the only ways to boost the bottom line is by improving the life of the shredder. This is why we use Hardox® HiTuf steel for our components.”
He continues, “SSAB’s steel is the best we’ve ever used for these components, for a number of reasons。 First, it’s simply the best high-tensile wear-resistant plate in the world。 The stuff from the competition just doesn’t have the through-hardness that you need in a shredder。”
“Secondly, SSAB is the only manufacturer that produces this sort of highly resistant plate in the 100 mm and 120 mm thicknesses we need. This is critical to our designs because the extra thickness and extra toughness gives our shredders much longer life. Our wear plates and rotor disks keep on going when others have turned into scrap themselves.”
Pacific Shredder also praises SSAB’s technical expertise and support. “Whether it’s machining, welding, cutting, they make sure we understand everything we need to know about pre-heat, post-heat, welding wire types, and so on.”
Highly crack- and wear-resistant steel increased shredder durability
Longer equipment life boosted company’s bottom line
