SUS444
Ferritic stainless steel SUS444
00Cr18Mo2Characteristics of SUS444:
SUS444 is a type of ferritic stainless steel. It contains relatively low carbon and nitrogen. Its corrosion resistance is extremely excellent. The content of niobium or titanium is conductive to avoid intergranular corrosion after welding. The greatest advantage of SUS444 is that it has excellent resistance to chloride stress corrosion cracking. Moreover, its resistance to chloride pitting corrosion is superior to that of SUS304 due to high molybdenum content, and is equivalent to that of SUS316L. Accordingly, SUS444 is especially suitable for the application of various water treatment devices.Chemical compositions of SUS444 (%):
