Vanguard Premium Alloy Steel Wear Plate (500 HB)

SAS Global developed Vanguard Alloy Wear Plate to specifically meet the needs and challenges associated with extreme working environments. Vanguard is a water quenched, through-hardened, martensitic steel that is highly impact and abrasion resistant. The homogeneous hardness of Vanguard is achieved by its fine-grain microstructure, which is steadily cooled during its special quench and tempering process. Vanguard is also a very strong and tough wear plate due to its low phosphorus and sulphur content. The high hardness and strength of Vanguard allows it to outlast AR400 by 2 to 3 times. This allows a thinner, lighter weight liner plate to be utilized.

Bucket Wear Strip Case History:

Out Performs Brand X With 4X the Life

The CAT 930 bucket pictured on the left was only in service for 1200 hours at an Iron Ore Mine before it had to pulled out of service for maintenance.

Some of the protective Brand X strips are completely worn away and the parent metal of the bucket is now damaged. This bucket now requires extensive repair and new protective strips. 

The CAT 930 bucket pictured on the right was protected with SAS Vanguard Premium Alloy Wear Plate strips. It was in service for 2000 hours at the same Iron Ore Plant.  The bucket was inspected at this time and the Vanguard strips were only showing about 50% wear at the very most.

The buckets using 1” thick Brand X wear strips are being rebuilt every 3 months like clockwork. The buckets protected by the 1” thick Vanguard Wear Strips last close to a year before replacing.
