Our advantages
1. Technological leadership: breakthroughs in patented formulas and processes
Exclusive alloy formula: Backed by the prestigious Dutch invention patent (patent number: 2029411), this formula achieves an unparalleled balance of corrosion resistance, verified by a salt spray test lasting over 1000 hours, and exceptional high-temperature strength boasting a tensile strength of ≥ 790MPa. This is accomplished by the precise modulation of nickel, chromium, and molybdenum ratios (Ni ≥ 58%, Cr 20-23%, Mo 8-10%)—outperforming the ASTM B166 standard.
Advanced process guarantee: Utilizing the cutting-edge dual metallurgical process (VIM+ESR) and pioneering nano polishing technology, we ensure a composition of welding wire that is pure and surfaces that are exceptionally smooth with Ra ≤ 0.2 μm. This allows for precise tolerance control of ± 0.001mm, making it an ideal choice for high-precision automated welding applications.
2. Full scenario technical barriers: adapting to high-end manufacturing needs
Extreme environmental coverage: From deep-sea equipment, where it resists the corrosive effects of seawater, to aircraft engines, where it withstands high-temperature creep at 1000 ° C, this product meets the rigorous demands across sectors like petrochemicals, nuclear power, and new energy.
