Hardox® HiTemp

Hardox® HiTemp is a high-heat grade of Hardox® wear plate. It provides a cost-efficient solution for wear resistance at high temperatures up to 500°C (930°F) with a nominal hardness of 400 HBW. When traditional quenched and tempered wear-resistant steels lose hardness at higher temperatures, Hardox® HiTemp steel still delivers high wear resistance.

A high temp metal that can take the heat

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.

A heat resistant material for a wide variety of uses

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.

One of the best steels for high temperature applications

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

Heat resistant ceramics vs. our high temperature steel

Hardox® HiTemp can provide advantages over other materials like heat resistant ceramics or mild steel. For example, coke ramps made in thick basalt ceramic tiles are incredibly expensive, plus prone to cracking. This means more maintenance stops and money-wasting downtime. But with Hardox® HiTemp, you get a wear resistant steel that weighs less, yet stays strong and lasts long. And because of its workshop-friendly properties, you’ll have a quick and easy installation compared with materials like heat resistant ceramics that are common in high-temperature environments.

Benefits of Hardox® HiTemp high temp metal

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
