When it comes to fastening solutions in marine environments, corrosion resistance isn’t optional—it’s essential. That’s why 316 stainless steel stud bolts are the preferred choice for saltwater, high-humidity, and chemically aggressive conditions.
Thanks to factory customization, small batch flexibility, and fast delivery options, sourcing reliable marine-grade stud bolts has never been easier.
🌊 Why Choose 316 Stainless Steel for Marine Use?
Grade 316 stainless steel contains molybdenum (Mo), which significantly enhances its resistance to chloride-induced corrosion—making it ideal for offshore platforms, shipbuilding, harbors, and coastal structures.
Compared to 304 stainless steel, 316 offers:
- Better resistance to pitting and crevice corrosion
- Longer life in salt spray environments
- Excellent performance in acidic or alkaline media
