Abrasive elements in mining can damage mining infrastructure over time, such as earth-moving buckets and geological drill heads.
Further deterioration to mining materials can occur during their working life as a result of direct friction from geological strata or other components. This abrasion can lower overall throughput and efficiency of mining tools, and potentially lead to expensive maintenance procedures.
High-yield steels are routinely used in the fabrication of components designed to resist the distinct abrasive factors associated with the mining sector.
These components require extremely high mechanical strength and good degrees of formability to enable the production of complex steel shapes that can withstand both corrosion and abrasion.
This article takes an in-depth look at a high-yield steel grade that is ideally suited to the manufacture of mining components.

High-Yield Steel for Mining Components
High-yield steel grade S890QL is an exceptional structural steel that demonstrates high strength values in both quenched and tempered conditions.
Reinforcing the plates with S890QL steel helps to optimize the material’s abrasion-resistant qualities, ensuring ideal ratios of ductility, hardness, and physical integrity against mechanical agitation and geological abrasion.
This high-yield steel provides a distinct balance of extreme mechanical stability and good format availability, meaning that it can be welded and bent for increased component fabrication complexity, and still continue to offer excellent hardness and strength values.
These properties allow S890QL high-yield steel to be employed in the reinforcement of earth-moving and drilling equipment against abrasive media, heavy payloads, and the range of corrosive elements found in different geological strata.
S890QL high-yield steel’s strength values generally exceed those of standard structural steels more than threefold, as well as offering a low notch toughness testing temperature and a minimal yield strength of 890 MPa.
This high-yield steel is widely used in the mining and earth-moving sector and is compliant with EN 10025:6:2004 for hot-rolled steel products.
High-Yield Steel with Masteel
Masteel is committed to the rapid and consistent provision of high-quality steel products to any facility or mining location in the world. The company holds stock for a variety of industries, sourcing its high-yield steels from the highest-quality European mills.
Its S890QL high-yield steel is uniquely suited for use in the mining industry. High carbon contents of up to 0.20 % and molybdenum contents as high as 0.70 % ensure the corrosive resistance and mechanical hardness necessary to withstand the various weathering agents typically encountered in the mining industry.
Other grades of high-yield steel grades are also available, including S690QL, S960QL, S500MC, S550MC & S700MC.
