321 Stainless Steel Wire
321 stainless steel wire has very good stability. Under the condition of temperature of 427-816 °C and chromium carbide precipitation, it can maintain good resistance to intergranular corrosion. Due to the addition of titanium to the composition, the 321 alloy can still maintain stability in the case of chromium carbide formation.
