Cronatron® - 777 Austenitic High Impact Hard Facing Stick Rod Electrode, 43 to 47 (WH) HRC Hardness, 90 to 125 Amps, AC/DCRP Polarity, 1/8" (5 US Pounds)
Designed for low abrasion resistance and high impact situations.
Superior Advantages
• Work hardens under heavy impact conditions
• Unlimited pass-over-pass applications
• High operator appeal – smooth running, quiet and minimal sparks
For severe impact and extreme shock (torch cuttable)
Tensile Strength: 116,000 PSI Hardness: Rc 47 Polarity: AC or DC Reverse
Elongation: 38%
Typical Applications
• Bucket teeth
• Hammer mill and mill swing hammers
• Tampers and jackhammers
• Impactor crusher bars
Usage ProcedureUse AC or DC reverse polarity with normal maintenance welding procedures. Surface area should be clean and dry, however, CERTANIUM 777 is manufactured with special cleansing and fluxing agents to promote sound welds under most conditions. For vertical-down welding, hold a short arc and tilt the electrode 10° in the direction of travel, using a stringer bead technique.
Technical TipWhen joining manganese steels, use skip-welding technique to avoid temperature increase in a localized area. Do not preheat manganese steel. Interpass temperature should not exceed 500°F (260°C).
