Product Catalog
EXECUTIVE TUFF-WELD is a flux-cored, work hardening wire designed to resist impact, commonly referred to as a “Nickel-Chrome-Manganese”. No preheat required. Minimize heat input by quenching with water. Do not exceed 500°F interpass temperature. This high manganese wire will rapidly work harden.
Application and Features
Executive TUFF-WELD is typically used as the overlay on manganese steel, carbon, and low alloy steels subjected to severe impact. Specific uses include: crusher rolls and cones, railroad frogs and crossings, bucket teeth, and impact hammers. It is also used as a buildup for abrasion resistant alloys such as Executive MAX-WEAR.
