Stainless Steel Marine Rudder Stock
A marine rudder stock, often simply called a rudder stock, is a crucial component of a ship's steering system. It is the shaft or spindle to which the rudder is attached and which transmits the steering movements from the helm to the rudder, allowing the vessel to change direction. The rudder stock is connected to the rudder, typically at the top of the rudder blade. This connection allows the rudder to pivot around the stock, changing the angle of the rudder in the water.
Overview
The stainless steel is the primary materials of marine rudder stock, especially the 316L stainless steel. It is chosen because of its good corrosion resistant property as well as its strength and it’s widely available.
The mechanical properties and corrosion resistance of steel depend on the alloying elements and heat treatment. Alloy stainless steel can be obtained by adding carbon, chromium and nickel to iron and heating it properly. An oxide layer like aluminum does not act as a protection against corrosion, but the addition of chromium and nickel ensures that the metal itself does not oxidize.
Features:
Relatively high strength
Long service life
Low breakdown rate
Corrosion-resistant
Thermal stability
Fatigue resistant
Great compatibility with rudder and ships
