Abrasion Resistant (AR) Medium
AR Steel Plate
An abrasion resistant (AR) medium is used to cover carbon-manganese steel plates to provide abrasion resistance superior to that of most structural-quality carbon steels. Plates are intended for moderate wear applications where it offers improved wear resistance relative to an as-rolled structural carbon steel. These plates are not intended for structural applications and should not be used for structural or main load-bearing members. These plates can be ordered to AR 200 or AR 235 depending on the producing mill’s capabilities.
Chemical Requirements:
| AR 200 | AR 235 | |
|---|---|---|
| Carbon | .32 - .36 | .40 - .50 |
| Manganese | .90 - 1.30 | .60 - .90 |
| Phosphorous | .040 max | .040 max |
| Sulfur | .010 max | .050 max |
| Silicon | .35 max | .10 - .40 |
| Chromium | .25 max | |
| Nickel | .25 max | |
| Copper | .15 - .45 |
Note: Maximum thickness up to 1” incl.
Mechanical Requirements:
- AR 200 – HBW 200 nominal
- AR 235 – HBW 235 nominal
