Postalloy® Ultra-Shred 580

Postalloy® Ultra-Shred 580 is a non-cracking martensitic tool steel type alloy with numerous tightly packed carbides for excellent abrasion resistance under high impact. One layer deposits exhibit wear characteristics that would be expected from a chromium carbide hardfacing product. The alloy properties create a crack-free, fracture resistant cutting edge even under high heat conditions created by extreme friction.
