DESCRIPTION AND APPLICATIONS:

It is Rutile coated electrodes giving 25 Cr-12Ni deposit having excellent resistance to corrosion and oxidation up to 1100°C. The electrodes gives excellent Radiographic quality weld. Besides similar stainless steel, it is extensively used in dissimilar metal joining between MS and low alloy steel and steel stainless steel, overlaying and buffering application, welding straight chromium steel etc.

PRECAUTIONS:

  • Storing of Electrodes should be done in a warm storage room( temp. 120°C – 150°C) with low relative humidity to minimize the rise of moisture pick up
  • Electrodes slightly affected by moisture should be carefully dried for min. one hour at temp.250°C-300°C before use.
