Solas Stainless Steel Propellers Smooth, Durable, High Precision Overall Performance All SOLAS propellers are developed by a state of art process. Through a sequence of theoretical calculations, geometry design, prototype testing, pilot production and field tests, SOLAS propellers are designed to meet customers' various requirements. Modern CAD, CAM and CAE technologies are used to ensure that high precision tools are used for products. Reliability and Precision SOLAS Stainless Steel Propellers - Feature the industry's highest percentage of chromium, nickel, and molybdenum. Our material resists rust from salt water and increases the stability of the propeller blades. SOLAS Stainless Steel propellers are made by investment casting process. SOLAS focuses its production improvement efforts on efficient use of space, increased yield, first in first out processes and automated equipment (such as robotic dipping arms). We are constantly improving processes and striving even higher. Performance and durability are the characteristics of the SOLAS stainless steel products.
