Wear resistant steel plate guarantees its mechanical properties by quenching /quenching followed by tempering. The properties of the processed plates cannot be retained, if exposed to service or preheating temperatures in excess of 250°C. Heating beyond 200°C will have the slight reduction in hardness.


Standard low stress marking and paint marking on plates. Color coding provided for clear identification and traceability.


Optimally designed chemistry coupled with superior dimensional tolerances help in ease of fabrication. ROCKHARD 450 plates can also be offered in shot blasted and primer coated plates.


ROCKHARD 450 can be welded. Recommended to use low hydrogen welding consumable. Approximately 100°C is advisable temperature for pre-heating. Plates must be clean, free from rust, scale and moisture. Product can be welded with all fusion welding methods such as SAW (Submerged Arc Welding), GMAW (Gas Metal Arc Welding) and SMAW (Shielded Metal Arc Welding). For more information concerning welding and fabrication consult standard guide lines given for similar international standards.
