is a through hardened, abrasion resistant steel plate, offering long life expectancy in sliding and gouging abrasion applications.


BISPLATE 500 is the hardest steel produced by ISALLOY STEELS and offers exceptionally long life in sliding abrasion applications such as:

• Dump Truck Wear Liners
• Chutes
• Wear Liners
• Earthmoving Buckets
• Cutting Edges
• Ground Engaging Tools


BISPLATE 500 is a medium carbon, high hardness, abrasion resistant steel. With appropriate attention to heat input, preheat and consumable selections, BISPLATE 500 can be successfully welded to itself and a range of other steels by conventional techniques.

Because of its high hardness, cold forming of BISPLATE 500 is difficult, requiring higher bending and forming 
forces, and greater allowances must be made for springback.

If heating is necessary, this should not exceed 200ºC, otherwise mechanical properties may be affected.
