NC-70

Specification

Description

• NC-70 is a low hydrogen type electrode that uses mild steel core wire
• Good fusibility with base plate
• Suitable for repairing of welding cast iron parts, such as ingot cast

Application

• For build-up repairing of ingot cases and other cast iron products where machinability is required

Remarks

? Preheating at 200ºC and over is appropriate to prevent cracking

Satisfactory results can be obtained by use of buttering
