Alloy Steel Wear Blocks & Bars for the Harshest, Most Abrasive Operating Conditions.
NOVA provides unparalleled protection in a wide array of applications.

Wear Blocks creates material-on-material wear and prevents the detrimental channel wear common to traditional wear plates with grooves parallel to material flow. And, our thicker profile extends wear life in even the most extreme applications.

Our wear bars are ideal for:
Buckets (excavator, loader, dragline, and face shovel)
Crusher spider arm guards
Discharge chutes
Rock boxes
Grizzly bars on feeders/shredder/grinding mills
Sugarcane knife edges
Adapters and attachments
Dredging equipment
Screen-feed distribution
Hopper wear areas

WEAR BLOCK & PLATE
NOVA carry a wide range of cast white iron wear block and plate materials. The Chrome Moly blocks and plates are popular in replacing hard faced and clad plate areas. They can be fitted by studding, bolting systems such as Fish tail bolts or by welding to the mild steel back. These blocks and plates can last up to 6 times the normal life of traditional wear plate systems.

Typical Applications Include:
Chutes
Conveyors
Bins
Hardness: Typical 700 HB (63 Rc)

Technical Advantages
To ensure that our chocky bars have finely dispersed microstructure and ultra-consistent properties when compared with the most competitive brands, we conduct a post-bonding heat treatment process. Our alloy hardness (63 HRC minimum) delivers maximum abrasion protection, while the steel backing plate absorbs high impact and facilitates ease of fitting and use.

Customization
Wear block can be custom-designed to exact applications. Each block is quality-tested and regularly subjected to thorough chemical, microstructure, visual, harness, ultrasonic, and destructive examinations.
