Ferrite, austenite, and martensite are all examples of iron’s crystal structures, and all are found within different types of steel. One of the defining difference between these crystal structures is the amount of carbon they can absorb - a greater carbon content generally, though not always, makes a steel harder, but more brittle.See all results for this questionsp.info What are the different types of austenitic stainless steel?Austenitic stainless steels generally fall into one of three categories, either the chromium-nickel stainless steel of the 300 series, the manganese-chromium-nickel stainless steel of the 200 series, or certain specialty alloys.
