321 stainless steel round bar

The 321 stainless steel round bar is commonly utilized in aerospace, thermal, electrical, and structural applications. Reinforced with titanium, this alloy excels in high-temperature environments, providing exceptional resistance to cracking and corrosion. Available in both full size and custom cut lengths, the stainless steel round bar 321 is a versatile choice for various industries.

This round-shaped bar is made from the 321 stainless steel alloy (S32100), which is a stabilized stainless steel. Its primary advantage is its excellent resistance to intergranular corrosion, particularly after exposure to temperatures in the chromium carbide precipitation range of 800 to 1500°F (427 to 816°C). The addition of titanium stabilizes Type 321 against chromium carbide formation.
