ABRASION RESISTANT STEEL PATES is used in areas where there is likely to be a high degree of abrasion or wear of the steel plate. Steels with a high HB rating (Brinel Hardness) are intended for applications where wear or abrasion resistance is important. The benefit of using an abrasion resistant steel is that that the plant, machinery or constructions working life can be extended considerably. This can significantly improve the reliability, durability and safety of structures and equipment. It also helps to reduce the maintenance costs associated with wear and breakdown of plant. 400 HB steel is over 3 times harder than mild steel (120HB), but only a third as hard as stainless steel (1250HB).

Scope : COR-TEN A applies to plates up to 12.5mm in thickness, COR-TEN B applies to plates up to 50mm in thickness.

Weathering means that due to their chemical compositions COR-TEN A and COR-TEN B steels, when utilized unprotected, exhibits increased resistance to atmospheric corrosion compared to unalloyed steels. This is because it forms a protective layer on its surface under the influence of the weather.

Applications : The steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions. Basic guidelines for the use of this steel in the unprotected condition are described in EN 10025-5 and DASt rule 007.

Mechanical Properties :

• In the state of delivery condition At room temperature for plates ≥3mm in thickness (transverse test specimans, according to EN 10002).

The notched-bar impact energy is determined on ISO-V longitudinal test specimens at a temperature of - 20°C as an average of three tests. For product thicknesses ≥10mm the average value is at least 27 J. For thicknesses between 10mm and 6mm, the minimum impact value is reduced proportionally to the specimen width (product thickness).No impact test is performed on products below 6mm in thickness.

Number of Tests :

• 1 tensile test
• 1 test specimen per 40 t from each heat*)
• Notched bar impact test
• 1 set specimens per 40 t from each heat *)
• (3 specimens) (at test temperature -20°C) as
