444 ferritic stainless steel pipe is a highly corrosion-resistant ferritic stainless steel material with ultra-low carbon and nitrogen, 18% chromium and 2% molybdenum. The following is a detailed description of 444 ferritic stainless steel pipe:
Chemical composition and characteristics: 444 stainless steel (national standard grade 00Cr18Mo2) contains ultra-low carbon and nitrogen, 18% chromium and 2% molybdenum, as well as stabilizing elements of niobium or titanium. These ingredients give it excellent corrosion resistance, especially in chloride environments. In addition, 444 stainless steel is stabilized by adding niobium or titanium, which effectively avoids the problem of intergranular corrosion after welding.
Physical properties: The density of 444 stainless steel is about 7.7g/cm³, the thermal expansion coefficient is small, and the thermal conductivity is good. Compared with austenitic stainless steels such as SUS304 and SUS316L, 444 stainless steel has a lower thermal expansion coefficient and higher thermal conductivity, which makes it more advantageous in some occasions that need to withstand high temperature and high pressure.
Corrosion resistance: 444 stainless steel has excellent resistance to chloride ion stress corrosion cracking and pitting corrosion, and is particularly suitable for applications in high chloride media. Its resistance to chloride ion pitting corrosion is better than SUS304 and comparable to SUS316L.
Application areas: Due to its excellent corrosion resistance and physical properties, 444 ferritic stainless steel pipes are widely used in many fields. Including but not limited to water treatment devices, food processing equipment, heat exchangers, hot water storage containers, solar energy collection panels, and kitchen appliances. Especially in water treatment devices, 444 stainless steel is an ideal choice due to its excellent resistance to chloride ion corrosion.
Processing and welding performance: 444 stainless steel has good processing and welding properties, and can be welded using the welding method of ordinary stainless steel. This gives it greater flexibility and convenience in the manufacturing process.
