We stock a range of abrasion resistant steel plates for the quarrying, mining, and cement industries. The stock is held under cover in our purpose built warehouse in the Jebel Ali Free Zone giving immediate access to material for our customers throughout the U.A.E. and allowing us to efficiently ship plates throughout the Middle East.
Plates are supplied shot blasted and primer coated in specifications XAR 400, BMAC 400, and XAR 500 with a nominal Brinell hardness of 400 or 500 according to the grade.
Stock Range
400 Brinell steel
Thickness: 6 mm to 100 mm
Format: 6000 mm x 2500 mm
A smaller range of 500 Brinell steel is also available and both this and the 400 Brinell range are supplemented by stock available from our Group warehouses in the U.K. and South Africa where a huge range of abrasion resistant plates is also available. Plates from these locations can be supplied cut to size, formed, drilled, or machined for use in applications such as crusher parts and cutting edges.
Fabrication of 400 Brinell Abrasion Resistant Steel
Welding
400 Brinell steel can be welded under normal conditions using MMA, MOG, and SAW without preheat up to a combined thickness of 60mm provided hydrogen controlled electrodes are used. Consumables should be dried in accordance with scale ‘D’ of BS 5135. Consumables should be chosen on the basis of whether or not the weld metal is exposed to wear conditions.
Machining
Machining or drilling is more difficult due to hardness. For 400 Brinell use high-grade cobalt HSS E drilling tools.
Forming
Abrasion resistant steels can be readily cold formed. Compared with steels of lower yields, three factors should be considered:
- Higher press forces
- A greater bend radius is required
- Spring back.
Flame Cutting
Material can be cut using conventional flame cutting practices without the need for preheat at ambient temperature.
Cold Bending
Where possible, cold bending should be carried out with the bend axis perpendicular to the rolling direction, this being the less onerous of the two directions. The following table contains guidelines for bending to a 90°angle. In general, however, bending radii should be as generous as possible.
