SS Solid Balls
What is SS Solid Balls?
SS Solid Balls are precision-engineered spherical components made from high-grade stainless steel, designed for use in various industrial and mechanical applications requiring strength, smoothness, and corrosion resistance. They are commonly used in valve systems, bearings, grinding applications, and precision instruments. The uniformity in size, weight, and surface finish makes these balls ideal for high-performance, low-friction operations.
Asiad Steel Industries is a trusted manufacturer and supplier of SS Solid Balls in a wide range of diameters and grades, including SS 304, SS 316, SS 420, and SS 440C. Our solid balls are produced with tight dimensional tolerances and mirror-finish surfaces to ensure excellent performance across various industries.
