SS 321, also known as UNS S32100, is a titanium-stabilized variant of austenitic stainless steel. It combines the beneficial properties of stainless steel with added resistance to corrosion and oxidation in high-temperature environments. Its composition includes chromium, nickel, and a small amount of titanium, which allows it to perform exceptionally well in extreme conditions. One of the key features of SS 321 is its ability to withstand temperatures up to 900°C (1650°F) while maintaining its structural integrity. This makes it a perfect material choice for applications that are exposed to high-temperature environments, such as the aerospace, chemical processing, and power generation industries. Additionally, its titanium content helps prevent carbide precipitation, which can lead to sensitization and corrosion in stainless steels exposed to high temperatures.
SS 321 stainless steel stands out due to its impressive durability, resistance to high temperatures, and excellent corrosion resistance.
