Roc Mn, Roc 250, Roc 400, 401, 500 wear steel
Wear-resistant high strength steel grades Roc Mn, Roc 250, Roc 400, 401 and 500 stand out for its excellent performance properties, allowing it to be used in quite difficult operating conditions including abrasive wear.
The convincing wear resistance of metal contributes to the production of relatively light products, the required shape, with a sufficiently long service life.
Classification of metals by wear resistance is simplified thanks to the digital indexing of steel grades, indicating the hardness of the material, in units of the Brinell scale.
Special properties
Roc steel stands out for its excellent balance of strength, hardness, wear resistance and tool life to corrosion.
Besides, the metal is well processed, bent and welded. And the exclusion of heat treatment operations allows optimizing many production processes.
Application areas
All grades of Roc structural steel are successfully used in the production of armor plates for various purposes , excavator buckets, dump truck bodies, construction machinery knives, crushers, cutting edges and knives for processing equipment, containers, load-bearing elements of machinery and equipment.
