The chemical composition of stainless steel can be divided into two broad categories: austenitic and ferritic. While CF8M and CF3M are part of the austenitic family, they also differ in their composition. The main component that sets them apart from each other is chromium content; CF8M contains 8-10% chromium, while CF3M contains 3-4%.

The most significant difference is that A351 has tensile property, inspection, and quality requirements not found in A743. A351 references A703 which in turn sets out the testing & analysis methods and requirements. A743 references A781, a general specification for casting used in non-pressurized applications.
