Description
EN 1.4404 material (stainless steel X2CrNiMo17-12-2) is a low-carbon version of 1.4401 (X5CrNiMo17-12-2), the maximum carbon content is only 0.03%, while 1.4401 is 0.07% maximum, so the weldability and corrosion resistance of 1.4404 stainless steel is better than 1.4401. The chemical composition of material 1.4404 and 1.4401 contain molybdenum (Mo), while EN 1.4301 (X5CrNi18-10) and 1.4307 (X2CrNi18-9) do not. Molybdenum improves the heat resistance of steel and resists pitting and crevice corrosion in environments containing chlorides or other halides. The following tables and lists give the stainless steel 1.4404 datasheet including chemical composition, physical properties and mechanical properties etc. DIN EN 1.4404 material chemical composition is listed in the following table.
