316 Stainless Steel Sheet
316 stainless steel sheet (UNS S31600) contains 2.1-2.5% molybdenum, boasting corrosion resistance more than five times higher than that of 304 in chloride environments. It has passed the 2000-hour salt spray test (ASTM B117), making it a structural material specially designed for extreme environments. This sheet is highly suitable for highly corrosive scenarios such as marine engineering and medical implant devices, delivering exceptional performance where other materials fall short.
Extreme Performance Validation
Deep Ocean Applications
Can tolerate pressure at a depth of 6,000m (60MPa), making it reliable for deep-sea exploration equipment and underwater structures.
Resists Microbiologically Influenced Corrosion (MIC) at chloride concentrations >100,000ppm, ensuring longevity in harsh marine environments teeming with microorganisms.
Medical Implant Readiness
Holds ASTM F138 biocompatibility certification, meeting the strict standards required for use in medical implant devices, ensuring safety and compatibility with the human body.
Electropolished to Ra≤0.15μm (per SEMI F19), providing a smooth surface that minimizes irritation and supports better integration with biological tissues.
Aerospace & Beyond:
Exhibits thermal cycling resilience, withstanding temperatures ranging from -270°C to 450°C, making it suitable for aerospace components exposed to extreme temperature fluctuations.
Boasts radiation hardening, able to endure a neutron flux of 10¹⁹ nvt, ensuring stability in high-radiation environments such as nuclear facilities and space missions.
