Our advantages
1. Technological leadership: Through innovative breakthroughs in patented formulas and state-of-the-art processes, we lead the industry.
Exclusive alloy formula: With a prestigious Dutch invention patent (patent number: 2029411), our formula provides an optimal balance of corrosion resistance (salt spray test ≥ 1000 hours) and high-temperature strength (tensile strength ≥ 790MPa). This is achieved by precisely calibrating the nickel-chromium-molybdenum ratio (Ni ≥ 58%, Cr 20-23%, Mo 8-10%), delivering performance that exceeds ASTM B166 standards.
Advanced process guarantee: Utilizing a dual metallurgical process (VIM+ESR) alongside cutting-edge nano polishing technology, we ensure the welding wire's pure composition and unparalleled surface smoothness (Ra ≤ 0.2 μm), with tolerance control precision of ± 0.001mm. This makes it ideally suited for high-precision automated welding applications.
2. Full scenario technical barriers: Our solutions are tailored to meet the high-end manufacturing requirements.
Extreme environmental coverage: Our product excels in demanding environments, from deep-sea equipment resistant to seawater corrosion to aircraft engines that withstand 1000 °C high-temperature creep. It thrives in challenging fields like petrochemicals, nuclear power, and new energy sectors.
Multi-functional compatibility: Engineered to support welding of dissimilar metals (such as nickel-based alloys and stainless steel, 9% Ni steel overlay welding), it ensures uniform and stable weld formation, reduces sensitivity to hot cracks by 40%, and lowers subsequent processing costs.
3. Flexible production and full cycle service
Customization capability: Leveraging nearly two decades of technological expertise, we offer flexible solutions with non-standard specifications (diameter 0.6-4.0mm) and special coatings, with a rapid response cycle of just 3 days.
