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%.
scope: 1.1 This specification2 covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing parts (Note 1).
