Our advantages
1. Technological leadership: Pioneering breakthroughs in patented formulas and innovative processes
Exclusive alloy formula: With an esteemed Dutch patent (patent number: 2029411), this formula masterfully balances corrosion resistance (salt spray test ≥ 1000 hours) with formidable high temperature strength (tensile strength ≥ 790MPa). This is achieved through a precise calibration of the nickel, chromium, and molybdenum composition (Ni ≥ 58%, Cr 20-23%, Mo 8-10%), surpassing the ASTM B166 standard significantly.
Advanced process guarantee: Leveraging a dual metallurgical process (VIM+ESR) alongside cutting-edge nano polishing technology, this ensures unparalleled purity of the welding wire composition, a polished surface smoothness Ra ≤ 0.2 μm, and precise tolerance control ± 0.001mm, perfectly meeting high-precision automated welding demands.
2. Full scenario technical barriers: Tailored to meet the demanding needs of high-end manufacturing
Extreme environmental coverage: Whether in the depths of the ocean or within the extreme environments of aircraft engines (with resistance to 1000°C high-temperature creep), this wire stands resilient against the toughest conditions found in petrochemicals, nuclear power, and new energy sectors.
Multi-functional compatibility: Supports versatile welding of dissimilar metals, such as nickel-based alloys to stainless steel, or 9% Ni steel overlay welding. It ensures consistent and stable weld formations, reducing susceptibility to hot cracks by 40%, and considerably cutting down on subsequent processing costs.
3. Flexible production and full cycle service
Customization capability: With nearly two decades of technological expertise, we offer flexible non-standard specifications (diameter 0.6-4.0mm) and specialized coatings, with a brisk response cycle reduced to just 3 days.
