• FAQ of Stainless Steel Propeller

1. Difference Between Stainless Steel Propeller and Copper Propeller

· Under the condition of having the same tensile strength, stainless steel has better impact resistance.
· Under the condition of reducing the same temperature, the impact characteristics of stainless steel are not sensitive to low temperature.
· Under the same air bubble condition, the anti-cavitation and iron stripping ability of stainless steel is stronger.
· Under serve working conditions, stainless steel is more adaptable to the conditions.
· Under the condition of being in high-pollution seawater, stainless steel is more resistant to corrosion.
· Under high propulsion torque conditions, stainless steel is more suitable to the conditions.
· As to preventing the attachment of sea creatures, stainless steel has stronger ability.

2. Are stainless steel propellers better?

For better overall performance, stainless steel propellers are a better choice. Stainless steel propellers are more expensive, but are far stronger and more durable than aluminum. They will be able to tell you which pitch and material propis best for your outboard and your type of fishing.

3. What is the advantage of a stainless steel prop?

Stainless steel propellers are designed for high performance and they are the most durable choice on the market today. They have thinner blades which will reduce dragging and will not flex when you are traveling at high speeds.

4. Will a stainless steel prop increase speed?

As a rule, a stainless-steel prop (assuming the correct pitch and diameter) will make your boat go faster — up to 2-3 knots on some boats. Stainless steel is stronger and can be made thinner, allowing more speed. Stainless steel also flexes less and keeps its shape at higher speeds.

5. Is stainless steel more expensive than aluminum?

Aluminum vs Steel Cost
The price of steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore, however steel is generally cheaper (per pound) than aluminum (see galvanized vs stainless for more info on steel).

6. Can a stainless steel prop be repaired?

Generally speaking, stainless props are made from two general types of metals. High-carbon stainless is very strong and damage resistant. It welds well and cangenerally be repaired unless it is bent excessively. Given its high strength, it does not like being bent into a pretzel and straightened.
