What is the meaning of A351-CF8M?

A351-CF8M refers to a specific grade of stainless steel defined by the ASTM A351 standard, which outlines the chemical and mechanical properties of cast stainless steels. The "CF8M" designation indicates that the alloy is austenitic, containing approximately 18% chromium and 10% nickel, with the addition of molybdenum for enhanced corrosion resistance. This grade is often used in applications requiring good strength and resistance to pitting and crevice corrosion, such as in chemical processing and marine environments.
