Extreme Abrasion Resistant Chrome-Moly White Iron Wear Blocks
Wear Steel Blocks for the harshest, most abrasive operating conditions.
JADCO HardGuard Wear Steel Blocks, available in a wide array of shapes and sizes, are an extremely hard, laminated bi-metallic, wear-resistant composite with chrome-moly white iron bonded onto a mild-steel backing plate. Its bonding shear strength is over 30,500 psi (or 210 Mpa) and will not separate.
To ensure that our blocks have finely dispersed microstructure and ultra-consistent properties versus most competitive brands, we conduct rigid post-bonding heat treatment. Our alloy hardness (63 HRC, at a minimum) delivers maximum abrasion protection, while the steel backing plate absorbs high impact and facilitates ease of fitting and use. We do not recommend HardGuard block applications in working temperatures over 572°F (300° C).
Ideally, HardGuard Wear Steel Blocks work exceptionally well on buckets (excavator, loader, dragline, face shovel…), crusher spider arm guards, discharge chutes, rock boxes, grizzly bars on feeders/shredder/grinding mills, sugarcane knife edges, adaptors and attachments, dredging equipment, screen-feed distribution and hopper wear areas.
In addition, our blocks can be custom-designed to your exact application. Each block is quality-tested… and regularly subjected to thorough chemical, microstructure, visual, hardness, ultrasonic, and destructive examinations.
