Our advantages
1. Technological leadership: Achievements in patented formulas and groundbreaking processes.
Exclusive alloy formula: Featuring a prestigious Dutch invention patent (patent number: 2029411), this alloy formula is masterfully engineered to perfectly balance corrosion resistance (salt spray test ≥ 1000 hours) and high-temperature tensile strength (≥ 790MPa). It achieves this by meticulously adjusting the nickel, chromium, and molybdenum ratios (Ni ≥ 58%, Cr 20-23%, Mo 8-10%), outperforming the ASTM B166 standard.
Advanced process guarantee: By employing a dual metallurgical process (VIM+ESR) and state-of-the-art nano polishing technology, we ensure the welding wire's pure composition, optimal surface smoothness (Ra ≤ 0.2 μm), and precise tolerance control (± 0.001mm), perfectly suited for high-precision automated welding applications.
2. Full scenario technical barriers: Meeting the demands of high-end manufacturing.
Extreme environmental coverage: From deep-sea equipment impervious to seawater corrosion to aircraft engines resistant to 1000°C high-temperature creep, our solution meets the rigorous requirements of industries such as petrochemicals, nuclear power, and new energy.
Multi-functional compatibility: Designed to support welding of dissimilar metals (such as nickel-based alloys and stainless steel, 9% Ni steel overlay welding), this product ensures uniform weld formation, reduces sensitivity to hot cracks by 40%, and lowers subsequent processing costs.
