Unique Hardness Process
The exclusive Hard and Deep Process (HDP) was developed to maximize the hardness of the wheels, providing exceptional wear resistance and significantly extending their lifespan. This unique method ensures optimal performance even in the most demanding conditions.
HARDNESS OF HEAT TREATMENT HARDENED WHEELS
CROSS SECTION OF A 24” TD WHEEL
- The surface hardness of 58-62 RC gradually decreases to prevent tread chipping.
- The resulting casing is uniform and continuous over the entire tread and inner flanges, meeting the requirements of AISE Technical Report No. 6.
- The outer flange faces are not hardened, preserving the necessary ductile properties to prevent flange breakage.
- The bore, hub, webs, and outer flange faces are not hardened, making them strong and flexible (Hardness 200-260 BHN).
Our Hard and Deep heat treatment process, combined with Monorail’s high-carbon forged steel, allows us to achieve a very high surface hardness of 58-62 RC, while keeping the core hard and malleable. This hardness profile prevents flanges from breaking and also stops the tread from chipping. In conclusion, the Hard and Deep process covers all aspects of wheel heat treatment, ensuring the ideal hardness profile for a longer lifespan.
