Hardox® round bars
Hardox® steel round bars are versatile, ready-to-use high-strength steel rods that combine strength, high toughness, good bendability and good weldability in an absolutely unique way. They deliver the same high performance you would expect from Hardox® steel across a variety of abrasion-resistant and wear-resistant applications.
The all-round abrasion-resistant steel as round bar
Hardox® round bars allow you to upgrade your steel quality in different heavy-wear applications such as agriculture, engineering and machining, mining, drilling and construction. These abrasion-resistant steel round bars are tested frequently in each batch and come with guaranteed properties, as all engineering steels require.
Why Hardox® round bar?
- Come already through-hardened
- Easy to machine and weld, no preheating needed
- Exceptionally clean and fatigue resistance comparable with ingot casted steel
- Have same guaranteed properties as Hardox® wear plate
- Open up new design potential for stronger, lighter equipment
A versatile product, a variety of uses
The special properties of Hardox® abrasion-resistant round bar offer great advantages to fabricators and manufacturers in a diverse range of wear-resistant tools and attachments.
Speed up production of sieve or skeleton buckets
Recycling creates some of the toughest operating environments for equipment and machinery components. Glass recycling in particular comes with many challenges. Hardox® Extreme in glass recycling equipment delivers extreme performance so you can keep your valuable recycling equipment up and running longer.
Guaranteed strength and fatigue resistance
High-accuracy Hardox® steel round bars can be used in even more high-precision, tighter-tolerance applications as turned, ground and polished (TG&P) steel bars, thanks to renowned German machining center WSB.
Steel round bar a success in quick couplers
For earthmoving and attachment manufacturer Cerapid, conventional steel was too soft, and harder steel grades tended to crack too easily. But Hardox® steel round bar was just right in its hydraulic quick couplers – hard enough to withstand abrasion and penetration, yet tough enough to resist cracking. See how they got hooked on Hardox® in their hydraulic quick couplers.
Convenience and high performance, guaranteed
Hardox® abrasion-resistant round bars feature the same guaranteed properties as the trusted Hardox® wear plate. They come in two hardness levels: Hardox® 400 and Hardox® 500. Hardox® 400 is offered in diameters of 40–100 mm (1.575–3.937 in.) and Hardox® 500 in diameters of 40–160 mm (1.575–6.299 in.) Both round steel bars come in lengths up to 5,000 mm (196.85 in). The cleanliness and fatigue resistance of Hardox® steel round bars are comparable with ingot casted steel, combined with high strength and impact toughness.
Already hardened steel round bar
Engineering components subjected to high stress levels are traditionally hardened by heat treatment. But this only affects the surface of the material and fails to penetrate down to the core. Hardox® round bars are hardened steel round bars that are delivered already through-hardened. The hardness is consistent from the surface right down to the core of the material.
Tight tolerances for efficient, repeatable processing
Hardox® abrasion-resistant round bars can reach very tight tolerances. In cooperation with an expert machining center in Germany, we have succeeded in easily achieving tolerances of h11, h9 and f8 for the Hardox® 400 and 500 bars. This capability opens new opportunities for a wide range of applications using high-strength bright bar. Examples include axel, pin and coupling applications.
Delivery condition of metal round bars
- As-rolled or turned surface
- Pre-heat treated and ready to use, no extra quenching needed
Rod mills gain improved grinding performance with Hardox® round bars
A rod mill is an application that requires significant wear resistance, as well as high crack resistance and toughness.
