Apex Arc 22 Electrode

Austenitic ferritic electrode for high strength & crack resistance

Major applications:
For welding of high chromium – nickel steel, difficult and dissimilar steel and high strength armor steel. Applications include pressure vessels, earthmoving equipment’s dies, coil springs. Can be used as a buffer layer before hard facing and also for welding parts subjected to wear, heat, corrosion and impact

Alloy composition:
Fe, Cr, Ni, Mn

Mechanical properties:
UTS -750-850 n/Sq mm
Elong- 20-24%

Properties:
Weld metal contains controlled grain structure with excellent crack resistance. Weldability and machinability are superior. It gives smooth arc and less spatter without any undercut

Procedure:
Short arc will give the best result. For welding of alloy and high carbon steel, preheat the job.

Welding current:
AC/DC (+)
