TC 4800 is a high performance wear resistant steel, exhibiting a wear resistance 50% higher than that of conventional400HB water quenched steel.
Rather than relying exclusively on a high hardness level, properties of TC 4800 are improved as a result of the combination of an enriched alloying content (chromium, nickel, molybdenum and titanium) and specific heat treatment procedures. TC 4800 is designed to offer the best possible optimization of an exceptionalwear resistance and very acceptable workability.
The moderate hardness of TC 4800 in the asdelivered condition makes processing operations like cutting, machining and forming easier and far better than ordinary water quenched steels. When in service, TC 4800 strongly improves its wear resistance by a surface hardening effect of about +70 HB under the action of local plastic deformations caused by impact with rocks or pressure by the abrasive particles.
TC 4800 is ideal for applications in mines and quarries, cement and steel making industries, public works
and agricultural machinery. The grade i s suitable for all types of abrasion, sliding or impact, dry or wet
environments, including operating temperatures up to 350- 450°
