The role of sulfur and selenium in stainless steel cable ties cannot be underestimated

There are often impurity elements in general stainless steel cable ties, that is, sulfur and selenium. However, adding 0.2-0.4% sulfur to the stainless steel cable tie can improve the cutting performance of stainless steel, and selenium also has the same effect. Sulfur and selenium improve the cutting performance of stainless steel because they reduce the toughness of stainless steel. For example, the impact value of 18-8 chromium-nickel stainless steel can reach 30 kg/cm2. The impact value of 18-8 steel (0.084%C, 18.15%Cr, 9.25%Ni) containing 0.31% sulfur is 1.8 kg/cm2; 18-8 steel containing 0.22% selenium (0.094%C, 18.4%Cr, The impact value of 9% Ni) is 3.24 kg/cm².

Sulfur and selenium both reduce the corrosion resistance of stainless steel, so they are rarely used as alloying elements of stainless steel. Therefore, sulfur and selenium have an indispensable role in stainless steel cable tie.
