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

HS Schoch uses Hardox® round bar to replace parts previously cut and shaped from steel plate. Now, the round bars are simply cut to length and welded in place. The benefits? Less time-consuming and costly. The round shape helps extend service life. There are no edges and the handled material slides more easily. No high-temp welding needed.

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.

Turned, ground and polished bars meet h9 tolerances

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

Инженерните компоненти, подложени на високи нива на напрежение, традиционно се закаляват чрез термична обработка. Но този процес засяга само повърхността на материала и не прониква до сърцевината. Кръглите пръти Hardox® са закалени стоманени пръти, които се доставят вече закалени по цялата си дебелина. Твърдостта е равномерна – от повърхността чак до сърцевината на материала.

Прецизни толеранси за ефективна и повторяема обработка

Износоустойчивите кръгли пръти Hardox® могат да достигнат много строги допустими отклонения. В сътрудничество с експертен център за механична обработка в Германия успяхме лесно да постигнем допустими отклонения от h11, h9 и f8 за прътите Hardox® 400 и 500. Тази способност открива нови възможности за широк спектър от приложения, използващи високоякостен шлифован прът. Примерите включват приложения за оси, щифтове и съединители.

Delivery condition of metal round bars

  • As-rolled or turned surface
  • Pre-heat treated and ready to use, no extra quenching needed

Защо да купите абразивоустойчив кръгъл прът Hardox® от SSAB

You might be considering buying conventional steel for rods, such as high-carbon steels like 42CrMo4V steel. These steels are an acceptable solution but can pose some serious limitations.

For one, you need an additional heat treatment to increase the bar’s strength, which usually results in an inconsistent hardness profile on the cross section. This will significantly impair the impact toughness levels, giving you a product whose quality you can’t rely on. And heat treatment is a costly, time-consuming process.
