Stainless steel boat propeller typically have high strength and hardness. This enables it to effectively resist deformation and damage when subjected to the enormous torque and thrust transmitted by the ship's main engine. SS boat propeller high-strength characteristics can ensure that the propeller can still work stably in complex ocean conditions, such as high-speed navigation on rough seas or starting propulsion when the ship is overloaded.
We are able to design and manufacture Stainless steel boat propeller.The diameter of this marine boat propeller can be from less than 1M to more than 5M. Boat propeller blades can be customized.
And Marine society class certificate for this boat propeller,ABS, BV, CCS, DNV(GL),NK,RINA are available.
1. High-strength: The tensile strength and yield strength of the stainless steel propeller are higher than those of copper alloy, providing better impact resistance. This can reduce the wear of the stern bearing and the rotational inertia of the boat propeller.
2. Long service life: The corrosion fatigue strength and anti-air bubble erosion performance of the stainless steel propeller are several times or even more than ten times that of the copper alloy. Especially in polluted seawater, it performs exceptionally well and can significantly extend the service life.
3. Low noise: The blades of the stainless steel propellers can be designed to be thinner and adopt a multi-blade design, which improves the propulsion efficiency while reducing vibration and noise.
4. Resistant to low temperatures: The brittle transformation temperature of the stainless steel alloy at low temperatures is relatively low, and its low-temperature impact toughness is high, making it suitable for use in cold environments.
5.High torque: Due to the high strength of stainless steel, it is conducive to designing large-angle blades, thereby enhancing the thrust.
6.The stainless steel propeller also has excellent corrosion resistance and can perform well in severely polluted seawater, reducing corrosion and damage.
Blade number | Advantages | Disadvantages |
3 | High speed efficiency, lightweight, low cost | Large vibration and insufficient thrust at low speed |
4 | Balanced efficiency and vibration, high overall cost performance | Harmonic noise is likely to be generated at medium speed |
5 | Low vibration, high thrust, good quietness | High cost and increased weight |
6 | Low cavitation noise, ultra-smooth operation | Slightly reduced efficiency and complex structure |
