Stainless Steel 321 is renowned for its stability, thanks to the addition of titanium which prevents harmful carbide precipitation during welding. This grade typically contains 17-19% chromium and 9-12% nickel. It boasts excellent mechanical strength, good ductility, and impressive corrosion resistance, even in high-temperature environments. These bars maintain their integrity under stress, making them a robust choice for fabrications that must perform reliably under demanding thermal and mechanical conditions.
