Cold Forming
Abrasion Resistant steel is very well suited for cold forming operations. The general minimum recommended R/t ratio when bending of High Abrasion Steel is given in the table below:
| Thickness (mm) | Transverse to rolling (R/t) | Longitudinal to rolling (R/t) | Trans. Width (W/t) | Long. Width (W/t) | |
|---|---|---|---|---|---|
| AR 400 | t < 8.0 | 3.5 | 3.0 | 8 | 10 |
| 8 ≤ t < 20 | 3.0 | 4.0 | 10 | 10 | |
| t ≥ 20.0 | 4.5 | 5.0 | 12 | 12 | |
| AR 450 | t < 8.0 | 3.5 | 4.0 | 10 | 10 |
| 8 ≤ t < 20 | 4.0 | 5.0 | 10 | 12 | |
| t ≥ 20.0 | 5.0 | 6.0 | 12 | 14 | |
| AR 500 | t ≤ 8.0 | 3,5 | 4,5 | 10 | 12 |
| 8 < t < 20 | 4,5 | 5 | 12 | 14 | |
| t ≥ 20 | 7 | 8 | 16 | 18 | |
Due to the homogeneous properties and narrow thickness.
tolerances of High Abrasion Steel, variations in springback is kept at a low.
level. Grinding of flame cut or a sheared edge in the bending area.
is recommended to further prevent cracking during bending.
Applications
High abrasion steel is recommended for following applications:
- Mining and earthmoving machinery
- Buckets, knives and grapples
- Dumper bodies and on road tippers
- Refuse haulers and scrap containers
- Screeners
- Crushing and pulverizing equipment
- Scrap presses
- Cement drum mixer barrels
- Feeders, skips and screw conveyers
- Conveyor belts
- Slurry pipe systems
Delivery Conditions
High Abrasion Steel is supplied as standard in the shotblasted and primed condition. In order to maintain a good weldability and laser cutting performance, a low zinc silicate primer is applied. Plates can also be delivered unpainted.
Ultrasonic Testing
In thickness from 8mm and above, all plates are UT tested and controlled against class S2, E2, according to EN 10160.
