Cronatron™ 344 Tool Steel Stick Rod Electrode

A broad selection of premium alloys to use for nearly any tool steel application and repair.
Superior Advantages
• Crack-resistant
• Premium operability
• High wear resistance
Hardness: Rc 59-63
Polarity: AC or DC Reverse
“D” and “M” Series
This alloy was formulated for welding the “D” and “M” Series, due to its very high percentage of carbon and alloy additions of chromium, molybdenum and vanadium. The deposits are air-hardenedable and require high preheat temperatures for welding types D-2, M-2.
Typical Applications
• Various tool steel repairs – specific alloy selection is dependent upon the type (or Series) of tool steel being repaired
• Forming dies, cutting tools and high impact tools
Usage Procedure
When used on hardened tool steels, preheat the steel to 150°F (65°C) below the draw temperature of the steel. Base metal should be cleaned to remove oil and other contaminants. Sharp edges should be removed where possible and chipped, spalled, or fatigued metal should be removed by grinding or other mechanical means. Deposits should be peened after each pass immediately after deposition to relieve stresses. Use care in removing slag thoroughly between multiple passes.
