Stainless Steel Ball

Stainless steel ball are favored for their excellent toughness and corrosion resistance, even in their unhardened state to meet the demands of demanding applications. Through annealing treatment, its corrosion resistance can be further improved. Both non-annealed and annealed stainless steel balls are widely used in valves and related equipment.

These spheres are resistant to corrosive media such as oxidizing solutions, most organic chemicals, food and disinfectant solutions. They have moderate corrosion resistance to sulfuric acid. On request, non-magnetic properties are also available.
