KF-810/KCH-420-SX Saw Flux Cored Wire & Flux

Description

KF-810/KCH-420-SX
Weld metal has chemical composition that conforms AISI 420 martensitic stainless steel

Classification


Application and Features 

• Weld metal has chemical composition that conforms AISI 420 martensitic stainless steel
• It provides good slag removal, excellent crack resistance and unlimited deposition thickness
• It is suitable for the reclamation of continuous casting rolls, blast furnace domes, print rolls and gudgeon

Welding Position

Welding Instruction

• Please preheat at 200~250°C when the carbon content of the carbon steel work piece is over 0.8 wt% or the low alloy steel work piece is over 0.35wt%
• Preheat and interpass temperatures should be controlled between 200-250°C for massive work pieces and high curvature surface to prevent weld cracking caused by high stress

Application
- It is suitable for the reclamation of continuous casting rolls, blast furnace domes, print rolls and gudgeon
