What is abrasion-resistant steel?

Abrasion-resistant steel, also called wear-resistant steel, has increased hardness and toughness compared to conventional high-strength steel, lasting up to 4 times longer — where hardness is the ability to withstand rubbing or scraping and toughness is resilience against fracturing.

How is AR steel made?

Carbon is a key alloy for increasing the hardness of abrasion-resistant steels – but too much carbon reduces its tensile strength and toughness, making it brittle and vulnerable to cracking. Additional AR steel alloys include manganese, chrome, nickel, and boron in different proportions based on specific end-use goals of the wear-resistant grade.

Wear-resistant steels can be made a few different ways, including furnace-heating followed by quenching, or rolling followed by direct quenching. Quenching alters the steel’s molecular structure, increasing its hardness.

As hardness increases in traditional AR steels, their formability and weldability decrease, limiting their applications. But the toughness of Raex abrasion-resistant steels lets fabricators bend, form, and weld without losing its properties, making it suitable for more challenging applications.

The advantages of using wear-resistant steel

longer service life

Longer service life

Because it’s tougher and harder than conventional high-strength steel, wear-resistant steel can last up to 400% longer. Long-term savings from using AR steel include reduced material costs, lower maintenance costs and, most importantly, avoiding downtime.

higher payload

Higher payloads

Rather than trying to fight wear and tear with thicker layers of mild steel, AR steels can be used for higher abrasion-protection in thinner gauges. And thinner gauge components are lighter, in turn increasing the load capacities – of 10% to 20% or more – of the equipment they’re used on.

higher workshop productivity

Higher workshop productivity

Raex abrasion-resistant steel is exceptionally clean, making it easier to weld and cut. Its consistent thickness and excellent flatness enable precision cutting and bending – resulting in nice, even bends.

Where is AR steel used?

Wear-resistant steels are widely used industrial applications where there’s high friction (rubbing, scrapping) between a piece of equipment and the material the equipment is pushing, carrying, cutting or processing.
