Duratec WC

 

Description

Duratec WC is a solid extruded hard facing electrode with a high percentage tungsten carbide. The electrode deposits a highly abrasion resistant weld metal with no impact resistance. No more than two layers should be deposited over one another and deposits are subjected to relief cracking. Deposits may be made on cast iron, mild steel, low alloy steels and austenitic manganese steels without preheating. High carbon steels should be preheated to 500°C before welding and cooled down slowly. The weld fluidity is good and fumes are minimal.

 

Weld Metal Hardness
