A fully austenitic stainless steel electrode for reduce the fissuring encountered in weld

CLASSIFICATION : AWS/SFA-5.4: E 320-16
CHARACTERISTICS :

A fully austenitic stainless steel electrodes weld metal is 20 Cr, 34 Ni, 2.50 Mo, 3.50 Cu with Nb added to improve resistance to inter-granular corrosion. These alloying are primarily used to weld base metals of similar composition for applications where resistance to severe corrosion is required.

APPLICATION :
  • Suitable for a wide range of chemicals including sulfuric and sulfurous acids and their salts.
  • Welding can be used to weld both castings and wrought alloys.
  • Materials to be welded, ASTM A351.A 744 Grade CN-7M, BS 1504-332 C 11 Carpenter 20, 20cb, 20 cb-3 and similar properties alloys.
RE-DRY CONDITION : Re-Dry the electrode at 350°C for 1 hrs before use.
