Even in a harsh acidic environment and a wide temperature range, Stainless Steel 321/321H Round bars have a strong ability to perform efficiently. These 321 Stainless Steel Round Bars can be stress-relief annealed without carbide precipitation within the sensitization temperature range of 450°C to 800°C, minimising the risk of inter-granular corrosion. Stainless Steel 321 is an 18/8 austenitic steel with titanium as a stabiliser. This grade can withstand temperatures of up to 900°C in high-temperature applications. It also has good strength, aqueous corrosion resistance, scaling resistance, and phase stability. Stainless Steel 321H, on the other hand, is a variation of Stainless Steel 321. Grade 321H has a higher yet controlled carbon content, resulting in increased strength and resistance to high temperatures. Stainless Steel 321/321H, like other austenitic grades, offers excellent forming and welding properties. It’s also incredibly tough at cryogenic temperatures.
