TYPICAL APPLICATIONS
ASTM/ ASME, 316, CF3M, CF8M stainless steels, pulp and paper mill equipments, bleaching solutions, chemical mixers, paint and dye industries, etc.
WELDING PROCEDURE
• The base metal should be free from oil, grease or dirt
• Before welding. Keep a short arc - length. The deposited weld metal should be cleaned with stainless steel wire brush.
• Redry electrodes at 200°C / 2hrs.
REDRYING : 250°C / 2hrs., max 5 cycles, 10 hr. total
SCALING TEMPERATURE : Approx. 850°C in air.
CORROSION RESISTANCE
Good resistance to general corrosion, specially in the more severe environments e.g. dilute hot acids. Good resistance to chloride pitting corrosion.
