FAQ
Q: How does 316L compare to 304 stainless steel?
A: 316L contains 2-3% molybdenum for 5x superior chloride resistance, making it essential for marine environments.
Q: Can these withstand scuba diving?
A: Yes, they're pressure-tested to 50m depth equivalent – ideal for professional water sports.
Q: Do you offer plating options?
A: We recommend uncoated 316L for maximum corrosion resistance, but PVD gold/rose gold plating is available.
Q: What's your quality control process?
A: Every batch undergoes salt spray testing, metallurgical analysis, and stress testing – certificates provided.
Q: Can I get custom lengths?
A: We produce 16"-24" standard lengths with ±0.5" tolerance, but special sizes are achievable.
Q: How do you prevent tarnish?
A: Our electrochemical polishing creates a chromium oxide barrier that self-repairs when scratched.
