Product Description

 

Introduction: It is MIG,TIG wire for welding of Stainless steels . The weld metal is fix carbon by added Ti to avoid precipitation of chromium carbide from intercrystalline. That improve intercrystalline corrosion resistance of welding seam, and have excellent mechanical properties.

Usage: Suitable for welding same type stainless steel or alloys.
