CHE557MoV is a basic-coated fine-grained steel electrode for all-position DC+ welding.
Delivers excellent process performance with superior ductility, toughness, and crack resistance in deposited metal.
Applications:
On-site installation welding of 14MnMoVN medium-heavy plates in large hydropower turbine spiral cases
Critical structures requiring high crack resistance:
• 15MnVN/15MnV high-strength steel mining vehicles
• Chemical vessels etc.
Mechanical Performance of Deposit Metal
Tensile Strength MPa (N/mm²): 630
Yield Strength (MPa): 540
Elongation A (%): 24
Impact Energy (J): -40℃＝64
Chemical Composition (%)
Welding Parameters
Current Polarity: DC+ / AC
Precautions:
Baking: 350–380°C × 1–2 hours; immediate consumption after baking.
Pre-cleaning: Remove rust, oil, and moisture from base metal.
Non-preheat welding: Maintain continuous arc; minimize interpass dwell time (especially for initial passes).
Technique: Short arc with narrow bead weaving.
