Martensitic

Martensitic stainless steels have a body-centered tetragonal (BCT) structure. They contain 12–18% chromium, and have a higher carbon content (0.1–1.2%) than austenitic or ferritic stainless steels. Like the ferritic BCC structure, BCT is magnetic. Martensitic stainless steels are highly useful in situations where the strength of the steel is more important than its weldability or corrosion resistance. The major distinction is that martensitic stainless steel can be hardened by heat treatment because of their high carbon content. This makes them useful for a number of applications including aerospace parts, cutlery, and blades.

Duplex

Duplex stainless steels are the newest stainless steel type. They contain more chromium (19–32%) and molybdenum (up to 5%) than austenitic stainless steels, but significantly less nickel. Duplex stainless steels are sometimes referred to as austenitic-ferritic because they have a hybrid ferritic and austenitic crystalline structure. The roughly half-and-half mix of austenitic and ferritic phases in duplex stainless steels gives it unique advantages. They are more resistant to stress-corrosion cracking than austenitic grades, tougher than ferritic grades, and roughly two times stronger than a pure form of either. The key advantage of duplex stainless steels is corrosion resistance equal to, or exceeding, austenitic grades in the case of chloride exposure.
