Stainless steel 321 Ball valves are widely used in applications requiring high resistance to high temperature oxidation and corrosion. It is commonly used in the petroleum, aerospace, oil and gas, and power industries. These valves are ideal for handling harsh fluids such as acids and corrosive gases due to excellent chemical resistance. The titanium stabilizer in stainless steel 321 increases durable strength under cyclic heating, making the valves suitable for high-temperature pipelines, steam services and process lines involving aggressive media They are also used in food processing and pharmaceutical industry.
