Wear-resistant steel
What is wear-resistant steel?
Wear-resistant steel is a special type of steel designed specifically to withstand various forms of wear, such as abrasive wear. These steels are widely used in industries where materials are exposed to constant wear and heavy impacts. Such steels provide an optimal combination of hardness, strength, and toughness, allowing them to be used in demanding environments such as mining, construction, and recycling industries.
Special features and applications of wear-resistant steel
The special properties of wear-resistant steel vary between different steel grades. For example, the Hardox® series of wear-resistant steels, such as Hardox® 400, Hardox® 450, and Hardox® 500 Tuf, are known for their excellent wear resistance and structural properties. Hardox® 500 Tuf, which is the world's toughest wear plate, is suitable for the most demanding applications, such as truck and tipper bodies, mining dumpers, and agricultural machinery. Its ability to withstand impacts even at low temperatures makes it an outstanding material for heavy-duty use.
Hardox® 450, in turn, is a versatile steel that offers excellent resistance to both wear and impact, featuring great bendability and weldability. Hardox® 400, with a nominal hardness of 400 HBW, is suitable for moderate wear applications and provides good toughness.
Wear-resistant steels for challenging wear conditions
Hardox® 500 and Hardox® 550 provide excellent solutions for extreme wear. Hardox® 500 steel, with a nominal hardness of 500 HBW, ensures a long service life and good workability, making it a common choice for wear parts and liners.
Hardox® 550 stands out with its nominal hardness of 550 HBW and is especially suited for use in crusher and processing equipment liners and hammers, providing longer service life without sacrificing fracture toughness.
Wear-resistant steels for extreme wear resistance
Hardox® 600, with a nominal hardness of 600 HBW, combines outstanding wear resistance and unique toughness. It's suitable for demanding applications such as concrete brick molds and crushers. Hardox® Extreme takes wear resistance to the highest level with a nominal hardness of 60 HRC and is mainly used in liners where exceptional wear resistance is required.
Special wear-resistant steels: Hardox® HiTuf, HiAce, and HiTemp
Hardox® HiTuf is designed for thick plate applications where extreme toughness is required. Its guaranteed impact toughness makes it an excellent choice for structural wear plates in large mining buckets and demolition tools. Hardox® HiAce is developed to endure acidic and corrosive environments, such as in garbage trucks and recycling facilities, while Hardox® HiTemp withstands high temperatures up to 500 °C, maintaining its wear resistance.
Summary
Wear-resistant steel, especially those in the Hardox® series, offers remarkable durability, excellent wear resistance, and reliable performance for a wide range of industrial applications. Thanks to their innovative features, the use of such steels not only extends the lifespan of equipment but also improves efficiency and safety in demanding conditions. For these reasons, wear-resistant steels are essential materials in many industrial applications where wear resistance and strength are critical factors.
