Advanced technology in wear
FUJINAWA 4800 is a high performance wear resistant steel, exhibiting a wear resistance 50% higher than that of conventional 400HB water quenched steel.
Rather than relying exclusively on a high hardness level, properties of FUJINAWA 4800 are improved as a result of the combination of an enriched alloying content (chromium, nickel, molybdenum and titanium) and specific heat treatment procedures. FUJINAWA 4800 is designed to offer the best possible optimization of an exceptional wear resistance and very acceptable workability.
The moderate hardness of FUJINAWA 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, FUJINAWA 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.
FUJINAWA 4800 is ideal for applications in mines and quarries, cement and steelmaking industries, public works and agricultural machinery. The grade is suitable for all types of abrasion, sliding or impact, dry or wet environments, including operating temperatures up to 350 – 450°C.
