00Cr18Mo2、019Cr19Mo2NbTi、18Cr2Mo

● Characteristics and applications:

00Cr18Mo2 is an ultra-low carbon nitrogen, 18% chromium and 2% molybdenum, high corrosion resistance ferritic stainless steel. The steel grade is generally stabilized with niobium or titanium to avoid intergranular corrosion after welding. The steel grade is particularly suitable for various water treatment devices.
