2. Chemical Composition Formula (Unit: %)
| Element | Content Range | Function |
|---|---|---|
| Silicon (Si) | 11.00-13.00 | Core alloying element, reduces melting point, improves molten pool fluidity, and optimizes weld formation |
| Iron (Fe) | ＜0.60 | Controls impurity content, avoids brittle phases in welds, and ensures welding strength |
| Copper (Cu) | ＜0.30 | Reduces the risk of intergranular corrosion and improves weld corrosion resistance |
| Manganese (Mn) | ＜0.15 | Refines grains and enhances weld toughness |
| Magnesium (Mg) | ＜0.10 | Controls alloy hardness and prevents workpiece deformation after welding |
| Zinc (Zn) | ＜0.20 | Reduces impurity interference and ensures stability during welding |
| Beryllium (Be) | ＜0.0003 | Complies with environmental standards and avoids harmful gas emissions during welding |
| Titanium (Ti) | ＜0.15 | Refines molten pool grains and improves the mechanical properties of welds |
| Each Other Element | ＜0.05 | Strictly controls the total amount of impurities to ensure material purity |
| Total of Other Elements | ＜0.15 | Meets the maximum impurity limit requirements of AWS A 5.10 |
