• Weldability: Stable welding arc, little spatter, excellent slag removal &perfect welding appearance.
• Suitable parent material:45# steel(ASTM 1045,JIS S45C, DIN C45) or similar steel.
• Hardfacing thickness limit: No limit.
• Crack resistance: Perfect. Likewise depends on parent material, workpiece size, hardfacing thickness, welding process, etc.
• Machining: Turning, milling,
• Diameter&Package:φ1.6mm, 15Kg/Spool.

Application:
Suitable for hardfacing continuous casting rolls and alloy steel axles piston etc.

• φ1.6mm:deposit efficiency: 91%.
• φ1.6mm: deposit efficiency: 5kg/hour.

Notes:

1. Remove fatigue layer, slag, oil and rust before welding.
2. Welding crack may occur , not damage the wear resistance ability. Preheating and slow cooling can reduce the risk. Recommended preheating temperature ≥200℃.

3. Stored in cool and dry place, use up within three days once opened.

Remark: Chemical composition and hardness are tested according to prescribed standard, actual results might be vary depending on many factors, like weld procedure, temperature etc, please contact our sales before use it in the intended application
