Resist Corrosion. Endure Extremes.
The HD-1 high-silicon stainless steel is a novel corrosion-resistant material jointly developed by New Hongda and the Institute of Metal Research, Chinese Academy of Sciences. It demonstrates excellent long-term performance in high-temperature concentrated sulfuric acid applications.
Advanced Material Development
- Combines foreign high-Si tech with decades of in-house expertise.
- Produced via arc smelting, VOD refining, rolling, and pipe drawing.
Superior Performance
- Enhanced mechanical properties post solution treatment.
- Excellent weldability and cold/hot forming adaptability.
Industry-Specific Solution
- Solves short lifespan of sulfuric acid equipment (high-temp/concentration).
- Cost-effective composite flanges (HD-1 + 316L/304).
Welding Specification
- Manual TIG welding with custom-matched filler wires.
