We can supply abrasion resistant steel in the form of gas or plasma cut profiles to exacting tolerances or as formed, drilled, or machines parts. It is of course also available as plate straight from our stocks.
Utilised in applications such as tipper bodies, cutting edges, crushing machinery, and excavator buckets abrasion resistant plate from Brown McFarlane is sourced from Western European steel producers and is available in 400, 450, and 500 Brinell hardness, in thicknesses from 3 mm to 150 mm, and up to 12 metres by 3 metres in plate size.
We stock Abrazo plates manufactured by Tata Steel as well as proprietary brands from other steel plate manufacturers.
Fabrication of Abrasion Resistant Steel
Welding
Abrazo 400 can be welded under normal conditions (if you require advice on welding, machining or forming then please contact any one of our offices) 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 400BHN use high-grade cobalt HSS E drilling tools and for 500BHN hard metal drilling tools are necessary.
Forming
Abrasion 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. The following cutting parameters are recommended:-

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.
