Hardox® HiTemp

If you need to build heavy equipment that can fight wear in tough, high-temperature applications, take a look at Hardox^® HiTemp wear resistant steel. While traditional Q&T wear-resistant steels experience a loss of hardness at temperatures of 300-500°C (about 570-930°F), this high temp metal stays strong and hard to improve performance and extend the service life of costly equipment.

The outstanding performance of this heat resistant material is achieved by using high-quality raw material combined with a carefully controlled manufacturing process. And in your workshop, Hardox^® HiTemp can be cut, welded, machined and cold formed using the same kind of machinery as other Hardox^® grades and conventional AR steel.

Abrasive and hot materials like slag – leftover waste from metal smelting or refining with a highly angular shape and rough surface texture – are no match for high-temperature, high-strength Hardox^® HiTemp in truck bodies. With a redesigned body using a thinner plate in the body’s flooring and sides, you can get more payload when the truck is fully loaded. Plus, the thinner plate lowers the overall weight of the truck when it travels empty.

In coking plant equipment, Hardox^® HiTemp provides a cost-effective, long-lasting solution in coke ramps, quenching wagons, cooling beds, slag tippers, furnace inlet scrapers and other heat-affected equipment. In short, Hardox^® HiTemp makes a great choice wherever you need optimal wear resistance and high structural strength.

Altus in Singapore saved 40% weight or 2.236 kg (4,930 lbs) by switching from 25 mm (0.984”) mild steel to 10 mm (0.394”) Hardox^® HiTemp in the slag dumper’s floor and from 12.7 (0.5”) to 10 mm (0.394”) in the sides.

Hardox^® HiTemp is one of the best steels for high temperature applications involving moderate wear, especially in process industries like steel, cement, asphalt, coal power or recycling. Applications for this high temp metal include:

• Dryer drums and lifter plates inside dryers in asphalt plants
• Clinker cooler plates and other liner plates in cement plants
• Blast furnace components and slag buckets in steel plants
• Rotary seal valves in coking plants
• Liner plates, ash handling equipment and chain conveyers in power plants
• Scrapers, screeners and liner plates in foundries
• Liner plates, gypsum and clinker hammers in crushers

• Can withstand the deformation that leads to buckling and cracks at high temperatures
• With high-strength steel in thinner plates, you can lower product weight while maintaining strength and durability to prolong service life
• Since it has a low carbon equivalent, it can be thermally cut without pre-heating within the whole dimension range – also suitable when much welding is needed
• Can be welded and cold formed using conventional methods and machinery
• Workshop-friendly properties enable quick and easy installation compared with other materials (like heat resistant ceramics) that are common in high temperature environments
• Helps to reduce costs, increase uptime and improve safety thanks to less frequent shutdowns for maintenance and repairs
