1.4435 is an acid-resisting austenitic CrNiMo-Steel with 18% Cr, approx. 14% Ni and at least 2.5% Mo. Due to the increased Mo-content, this material has a significantly improved corrosion resistance compared to other CrNi-Steels. 1.4435 is particularly resistant to reducing effecting organic and anorganic organic acids as well as against halogen-containing media. Furthermore, this steel is also less susceptible to pitting. The very low carbon content also improves the resistance to intergranular corrosion, allowing the use of this steel at elevated temperatures up to 450 ° C in continuous operation. 1.4435 can also be very well polished, very good deformable and can be welded excellent.
