Steel Properties
1.4404 is an acid-resisting austenitic stainless steel with 17% Cr, 12% Ni and 2,0% Mo. Due to its Mo content, this material has a significantly improved corrosion resistance compared to stainless steels. 1.4404 is resistant to reducing action of organic and inorganic acids as well as against halogen-containing media. Furthermore, this steel is less susceptible to pitting. The low carbon content also improves the resistance to intergranular corrosion and allows use at higher temperatures up to 450 ° C in continuous operation.
