2. Core Performance and Advantages
1. Scientific Chemical Composition of Deposited Metal
The proportion of chemical components is strictly controlled to ensure welding quality from the source. The specific components are as follows (Unit: %):
| Element | Content Range | Core Function |
|---|---|---|
| Carbon (C) | ≤0.12 | Reduces the risk of intergranular corrosion in welded joints |
| Chromium (Cr) | 23.0-25.0 | Improves the corrosion resistance and high-temperature strength of deposited metal |
| Nickel (Ni) | 12.0-14.0 | Cooperates with chromium to optimize corrosion resistance and enhance weld toughness |
| Molybdenum (Mo) | ≤0.75 | Improves the welding process performance of the wire and enhances weld strength |
| Manganese (Mn) | 1.0-2.5 | Enhances weld toughness and optimizes welding forming effect |
| Silicon (Si) | 0.30-0.65 | Improves the fluidity of the welding wire and ensures welding stability |
| Phosphorus (P) | ≤0.03 | Reduces the risk of weld cracks |
| Sulfur (S) | ≤0.03 | Reduces weld brittleness and improves joint reliability |
2. Outstanding Welding Performance
Stable Arc: The arc remains stable during the welding process, reducing spatter, minimizing subsequent cleaning work, and improving work efficiency.
Strong Adaptability to Working Conditions: Welded joints can withstand harsh environments such as high temperature and corrosion, maintaining structural stability for a long time and being suitable for complex industrial scenarios.
High Process Compatibility: It is recommended to use Ar + 0.5-2% O₂ mixed gas shielded welding, which isolates the oxidation and nitridation of the molten pool by air, ensuring the appearance and internal quality of the weld.
3. Application Scenarios
Designed specifically for dissimilar metal welding and also suitable for welding of specific stainless steel materials. The core applications include:
Dissimilar metal butt welding: Such as the welding of mild steel and Cr-Mo steel, which can alleviate the stress difference between the two metals, reduce welding deformation, and form high-strength and high-sealing joints.
Stainless steel welding: Suitable for welding stainless steel materials such as SUS309S and SCS17. Typical application scenarios include:
Corrosion-resistant components of chemical equipment (e.g., reaction kettles, delivery pipelines)
Structural parts of high-temperature furnaces (e.g., heating furnace liners, furnace frames)
Industrial corrosion-resistant pipelines and containers
4. Packaging and Delivery
| Item | Specific Description |
|---|---|
| Packaging Specifications | Two options available: 5kg/spool (suitable for small-scale operations and narrow spaces); 15kg/spool (suitable for large-scale continuous production, reducing the frequency of spool replacement) |
| Delivery Cycle | 25 days (stable cycle facilitates enterprises to plan production schedules and avoid delays in raw material supply) |
5. Quality Assurance
System Certification: The enterprise has passed the ISO 9001 Quality Management System Certification, and the entire process from raw material procurement, production and processing to finished product inspection complies with international advanced standards.
Quality Consistency: Each spool of welding wire undergoes strict testing to ensure uniform diameter accuracy, chemical composition and welding performance, eliminating the impact of batch differences.
