Do stainless steel cable trays need passivation
Although stainless steel cable is ideally suited to passivation, the acid used and degree to which the cable is exposed to it is determined by the grade of stainless steel. 304 stainless steel, for example, has a 18% chromium content, whereas 316 has 16% of the same element. Passivation, a treatment involving chemicals, improves its ability to withstand corrosion, increasing its longevity in tough conditions. This white paper compares the High Resistance (HR) and Hot-Dip Galvanising (HDG) solutions and highlights the new High Resistance range, ZnAl. According to ASTM A 380, passivation is “the removal of exogenous iron or iron com-pounds from the surface of a stainless steel by means of a chemical dissolution, most typically by a treatment with an acid solution that will remove the surface contamination but will not significantly affect the.
