The C95800 check valves is made of a high-strength nickel-aluminum bronze casting alloy. It is renowned for its excellent seawater corrosion resistance, high load capacity, and resistance to cavitation and wear.
Freeman Valve's C95800 check valves exhibits exceptional resistance to seawater and chlorinated fluids, making it particularly suitable for marine environments.
Freeman Valve's C95800 check valves is resistant to cavitation and erosion corrosion, making it suitable for high-velocity media.
Freeman Valve's C95800 check valves boasts high tensile strength (up to 620 MPa and above) and a hardness exceeding HB 200, making it suitable for high-load, high-wear conditions. Furthermore, it exhibits excellent fatigue resistance, making it suitable for dynamically loaded components.
When used in marine components, Freeman Valve's C95800 check valves resists marine organism adhesion, reducing maintenance requirements.
3.1 C95800 check valves are not suitable for operating conditions exceeding 260℃. This is because the strength and corrosion resistance of C95800 check valves decrease significantly at high temperatures.
3.2 C95800 check valves are not suitable for strong acids, oxidizing media, or ammonia-containing media (as they are prone to stress corrosion cracking).
3.3 C95800 check valves are not suitable for polluted seawater. Localized corrosion may occur under low-velocity sediment conditions.
The corrosion resistance of C95800 check valves mainly relies on the dense oxide film (Al₂O₃ + Cu₂O) formed on its surface, which remains stable even in acidic environments.
Good corrosion resistance (≤10% concentration, room temperature), superior to ordinary bronze; corrosion rate accelerates at high concentrations or high temperatures. However, factors such as temperature, concentration, and oxidizing properties (e.g., air circulation accelerates corrosion) need to be considered.
Moderate corrosion resistance (especially at >5% concentration or high temperatures); Cl⁻ will damage the passivation film, but better than 304 stainless steel. However, factors such as Cl⁻ concentration, pH value, and flow rate (erosion corrosion) need to be considered.
Excellent performance, suitable for low to medium concentration phosphoric acid environments. However, factors such as impurities need to be considered (e.g., fluorides can exacerbate corrosion);
Not corrosion-resistant (strong oxidizing acids damage the Cu-Al film), only suitable for very low concentrations. Concentration needs to be monitored; rapid corrosion occurs when the concentration > 5%;
Good corrosion resistance, suitable for food/chemical equipment. However, key influencing factors such as temperature and oxygen content need to be considered.
The corrosion resistance of C95800 check valves in acidic media stems from its Al-Ni synergistic passivation effect, making it particularly suitable for low-concentration non-oxidizing acids (such as H₂SO₄, H₃PO₄) and weakly acidic environments containing Cl⁻, but strong oxidizing acids must be avoided. In acidic conditions in chemical, marine, and other fields, its comprehensive performance (corrosion resistance + wear resistance + strength) makes it a cost-effective choice, but nickel-based alloys or titanium materials should be considered for extreme conditions.
