444 Ferritic grades Stainless steel is an ultra-low carbon nitrogen, 18% chromium and 2% molybdenum, high corrosion resistant ferrite stainless steel. The steel is usually stabilized by niobium or titanium, which can avoid the intergranular corrosion after welding. The steel is especially suitable for various water treatment devices.
