Short answer: Abrasion resistant steel is a high-hardness plate (AR400, AR450, AR500) made to resist sliding and impact wear in mining and handling equipment, supplied by our Abrasion Resistant Steel Supplier page; pick the grade by wear severity and back it up with the alloy basis in our Carbon Steel Supplier page.
At a Glance
What Abrasion Resistant Steel Is
Abrasion resistant (AR) steel is a low-alloy, through-hardened plate with a surface hardness of 360 to 540 HBW. It trades some ductility for a much longer service life where material slides, scrapes or impacts the surface. The base chemistry is covered in our Carbon Steel Supplier page.
How to Choose the Grade
Match hardness to the duty: AR400 for moderate sliding wear, AR450 for mixed impact and AR500 for severe abrasive conditions such as ore and shot. The comparison below shows why it beats mild steel for wear parts.
| Недвижимость | AR steel | Mild steel |
|---|---|---|
| Твердость | 400 to 540 HBW | 120 to 180 HBW |
| Wear life | Высокий | Низкий |
| Свариваемость | With prep | Easy |
Типовые применения
AR plate is used for excavator buckets, tipper bodies, chutes, hoppers, screen decks and wear liners. Fabrication and welding notes are in our Metal Welding Guide and surface care in our Metal Surface Treatment Guide.
Welding and Repair
Weld with low-hydrogen electrodes and preheat thicker sections; for worn surfaces use the consumables in our Hardfacing Wire Guide. The heat treatment behind repairs is in our Heat Treatment Steel Guide.
Specifying and Sourcing
State hardness, thickness and any certification; compare stock forms in our Steel Plate Buyers Guide, plan quantity with our MOQ and Lead Time Guide and price with our Price Quotation Guide.

Часто задаваемые вопросы
A plate with about 360 to 440 HBW surface hardness for moderate wear.
AR500 is harder and lasts longer under severe abrasion but is less formable.
Yes with low-hydrogen rods and preheat on thick plate.
No – it is a carbon-based wear steel, not corrosion grade.
