What is AR600 Steel Plate?
AR600 steel plate is a premium-grade abrasion resistant (AR) steel specifically engineered to withstand extreme wear and tear in the toughest environments. With a surface hardness between 570–640 Brinell (BHN), AR600 is among the hardest commercially available steel plates on the market.
While it’s less formable than lower-hardness grades, AR600 excels in applications where impact, gouging, and scraping occur regularly, such as in mining buckets, chutes, dump bodies, and aggregate removal systems.
Available Sizes
| Grade | Thickness | Width | Length |
|---|---|---|---|
| AR600 | 3/16″ – 3/4″ | 48″ – 96″ | Up to 480″ |
Note: Custom dimensions may be available upon request.
