00Cr19Ni13Mo3、022Cr19Ni13Mo3、00Cr17Ni14Mo3

Characteristics and scope of application:
00Cr19Ni13Mo3 is an austenitic stainless steel based on molybdenum. Compared with conventional chromium-nickel austenitic stainless steel such as 0Cr18Ni9, it has stronger chemical resistance. In addition, compared with conventional stainless steel, 00Cr19Ni13Mo3 has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is a low carbon grade or L grade. This grade has anti-sensitization properties during welding and heat treatment.
The 00Cr19Ni13Mo3 steel grade has good seawater resistance and SCC resistance compared to 00Cr17Ni14Mo2, and is used in chemical equipment that requires high corrosion resistance, such as Chemical ships and Chemical products.
