Dursteel Tuffplate – Wear resistant steel
DURSTEEL Tuffplate is a quenched and tempered steel with high abrasion resistance and a nominal hardness of 340 HB as well as very good toughness (impact resistance). Resistant to severe wear conditions or wear combining impact and abrasion, the extreme quality of the hardening and the specific metallurgy allow a good transformation of DURSTEEL Tuffplate, in particular a greater processability (oxyfuel cutting, weldability) than traditional 400 HB steels. It is a grade that is particularly appropriate for thicker components. DURSTEEL TUFFPLATE maintains its properties up to a temperature of 250°C. The use of DURSTEEL TUFFPLATE for heat treatment or hot dip galvanising is not recommended. For all uses of abrasion steels at higher temperatures, we advise you to use CREUSABRO product range or DURANOX 12.
