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. 1.4404 can be cold worked and weld excellent. This material is mainly used in the chemical, textile and paper industries, and is often used in apparatus, in sanitary industry and in pipe fabrication.
