F.3539-X2CrNiMo18 16 4、03X16H15M3

Characteristics and scope of application:
03X16H15M3 is an austenitic stainless steel based on molybdenum. Compared with conventional chromium-nickel austenitic stainless steel such as 08X18H10, it has stronger chemical resistance. In addition, compared with conventional stainless steel, 03X16H15M3 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 03X16H15M3 steel type has good seawater resistance and SCC resistance compared to 03X17H13H2, and is used in chemical equipment that requires high corrosion resistance, such as Chemical ships and Chemical products.
