Stainless Steel Electrodes

SIA

AWS: SFA 5.4 E307-15(Nearest) IS: 5206 E18.8 MnB20

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 o 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.
