Thanks to extensive studies on the characteristics of stainless steels and market needs, Rodacciai has invented and patented Rodinox®℗, a low-nickel austenitic stainless steel wire with mechanical and corrosion resistance characteristics similar to those of 1.4301 (AISI 304), which it can replace in most cases. The austenitic structure is obtained through an opportune balancing of Ni (lower than 304), Mn, Cu, and N (higher than 304) contents; the other elements are similar to 304. In addition to the complete range of drawn wire products used for household goods, appliances, grills, racks, bicycle spokes, clothesline wires, etc., Rodacciai has also developed Rodinox Plus® in bars, with improved machinability by chip removal characteristics.
