Relia® Quality Wear Resistant Plates
Relia® is a range of high hardness, conventional low-alloyed martensitic steels, which obtain their hardness through intense water quenching during plate manufacturing. Relia® steel plates offer outstanding resistance to abrasion typically 3 to 6 times higher than 355MPa-class construction steel, although the actual performance may vary depending on the type of wear and operating conditions. The use of Relia® plates will extend the service life of wear parts and machinery components over standard construction steel, without sacrificing on quick and easy fabrication in the workshop. Relia® plates are available in 3 nominal hardness levels 400, 450 and 500 HBW and 2 product specification levels to meet a wide range of practical requirements:structural parts.
Relia® Premium is the preferred solution for consistent and reliable processing behavior in the workshop combined with optimal in service performance.
Relia® 400, 450, 500 and the Relia® Premium series are proprietary grades developed by Industeel. There exists no engineering standard for plates intended for wear resistant applications.
