Postalloy® Super-Edge is a non-cracking abrasion resistant, gas-shielded, modified high speed tool steel welding wire designed for applications where edge retention is a primary concern. Weld deposits are martensitic with micro-carbides evenly dispersed throughout the deposit. These properties create a crack-free fracture resistant cutting edge even under high compression loads.
