Marine Stainless Steel Propeller Brief introduction
As we know, the corrosion resistance of copper alloy stronger than that of stainless steel, However the Anti-corrosion fatigue strength and cavitation erosion are not. Even several fold better than the copper alloy. Recent years, because of the pollution of the rivers and sea has intensified, Corrosion resistance of copper alloys becomes a problem that leads to the stainless steel propeller is used generally.
Products Superiority
Lower price. The price of stainless steel is one third of copper alloy.
High-strength. It is beneficial to the design of the inclined Angle oar, blade thickness can be reduced to improve propulsive efficiency and to decrease noise and shakiness.
Long service life. It can be used longer than copper alloy.
Giant propeller. Making giant propeller by using welding method.
