Strata 885 Cast Iron Arc Electrodes

Key Features

• Pure nickel electrode with non-conductive coating
• Suitable for all weldable cast irons
• Desposits are soft and machineable
• Non-conductive coating makes it magnificent for welds in difficult positions or deep recesses
• Good wetting on the base material due to the electrode melting slowly
• Tensile Strength: 49,000PSI
• Harness HV (HRC): 140 - 160 (75 - 80)
• Available in 2.5mm and 3.2mm
• Available in 1kg packs
• AWS: A5.15 ENiC1

Procedures

• Clean base metal before welding
• Keep bead length less than 50mm to disperse welding heat. Adopt back step, stepping stone, or symmetry methods by turns
• Hot peen in every pass
• It is not necessary to preheat and postheat in general but satisfactory results can be obtained by preheating at 100-200QC in accordance with the kind, shape, and size of base metal

Applications

• Hot and cold welding of gray cast iron
• Joining and surfacing of machines
• Frames
• Housing of gray cast iron, bearing blocks etc
