POSTALLOY®
SUPER-EDGE
Description

POSTALLOY® Super-Edge is an 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 fracture resistant cutting edge even under high compressive loads.
