SIA is a basic coated multipurpose stainless steel electrode producing a weld metal of 18Cr-9Ni-5Mn. The weld metal has excellent crack resistance and has good scaling resistance up to 850°C. Ideal for joining ferritic to austenitic steels, armour plates, austenitic manganese steels, heat resistant steels, dissimilar materials, for buffer layers etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.

2. Use low current , short arc and stringer beads.
