Product Introduction
| Performance Category | Key Indicator | Standard Requirement (Minimum Value) | Practical Notes (For Reference) |
|---|---|---|---|
| Strength Performance | Tensile Strength | 415 MPa (60 ksi) | Compatible with low-carbon steels such as Q235 and A36, meeting load-bearing needs of general structures |
| Strength Performance | Yield Strength | 345 MPa (50 ksi) | Prevents plastic deformation of the structure under load |
| Ductility Performance | Elongation (200mm Gauge Length) | ≥22% | Provides sufficient deformation capacity before weld fracture, reducing brittle cracking risk |
| Toughness Performance | Impact Toughness (V-notch) | ≥27 J at 0°C | Suitable for normal temperature/mild low-temperature (-10°C and above) scenarios. For use below -20°C, select low-temperature dedicated grades. |
Important Usage Notes
Welding Polarity: Only compatible with Alternating Current (AC) or Direct Current Electrode Negative (DCEN). Incorrect polarity will reduce strength and toughness.
Preheating Requirement: When welding base metals with thickness ＞ 12mm, preheating to 80-150°C is recommended to avoid weld cracking.
Application Scenarios: Suitable for normal-temperature working conditions such as steel structures and pipe root passes. For low-temperature/high-stress scenarios, confirm the electrode grade in advance.
