304 and 316

The two most common stainless steels—304 and 316—are both austenitic grades. The primary driver behind the popularity of austenitic stainless steels is the ease with which they can be formed and welded, making them ideal for high-efficiency manufacturing. There are many sub-groups of austenitic stainless steels with wide variations in carbon content. The properties are further tuned by the addition of alloying elements such as molybdenum, titanium, and copper. Austenitic stainless steels are frequently used to produce kitchen sinks, window frames, food processing equipment, and chemical tanks. They are also commonly used for outdoor site furnishings such as benches, stainless steel bollards and bike racks.

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.
