BISPLATE 450

BISPLATE 450 is a through hardened abrasion resistant steel plate with guaranteed high impact toughness.

Application

Long life expectancy in high impact abrasion applications makes BISPLATE 450 the ideal choice for a variety of applications, including:

• Dump Truck Bodies & Dump Truck Wear Liners
• Mining Buckets
• Tipper Bodies
• Cutting Edges
• Construction Waste Bins
• Liner Plates / Chutes

Fabrication

A unique chemical composition and steelmaking process for BISPLATE 450 has been developed, incorporating 
low carbon/low manganese contents. This is designed to improve transverse mechanical properties and produce low levels of segregation and ensures the newly developed BISPLATE 450 not only has superior mechanical properties but also good formability and weldability.

BISPLATE 450 can be readily welded using conventional low hydrogen MWAW and GMAW welding consum ables and processes. It can be welded to other weldable steels.

BISPLATE 450 can be cold bent by brake press-bending or roll bend method. However, BISPLATE 450 has higher hardness and strength levels compared to plain carbon steels and therefore suitable consideration of sufficient machine, plate bending direction and former radii must be made. BISPLATE 450 should be bent at room temperature or below 200ºC to avoid reduction of mechanical properties.
