Specifications by Type and Designation
1. The Brinell Hardness Value is an avarage of measurements taken from three points on the steel plate surface. A section of the surface from which the decarburized layer is ground off by about 0.7mm should be used as the specimen surface. Prior counsultation is recommended in the case of using thicknesses surpassing those listed above.
2. The Charpy Impact Test shall be applied to steel plates thicker than 12mm.
Increasing the thickness of the steel plate will lead to slight decrease in the hardness of the central portion of the plate. In the event that these steel plates need to perform at high tempratures, please cousult with us prior to placing your order. In the event that these steel plates need to perform at low temperatures, please select the Extra Tough Steel Plate options.

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:-

Milling :
Abrasion resistant steel can be machined by milling.
The following recommendations are given for general guidance:-

* For further information on 450, 500 please contact us for details.
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.
Bending direction (bend axis) |

Parallel to rolling direction | 4t | 10t |
