1. Austenitic Stainless Steel

Austenitic stainless steel is the largest category of stainless steels, making up about two-thirds of total stainless steel production. They possess an austenitic microstructure, a face-centered cubic crystal structure.

This micro-structure is comprehended by alloying steel with sufficient nickel or manganese and nitrogen to maintain an austenitic microstructure at all temperatures, ranging from the cryogenic region to the melting point. Thus, austenitic stainless steels are none hardenable by heat treatment since they possess the same microstructure at all temperature environments.

2. Yield Strength

Yield strength is low (200 to 300 MPa), which limits its use for structural and load-bearing components.

They are weldable by all processes; the most frequently used process is electric arc welding. They are essentially non-magnetic and maintain their ductility at cryogenic temperatures.

Their elongation is high, which allows for deformation in fabrication processes (such as deep drawing of kitchen sinks).

3. Ferritic Stainless Steels

Ferritic stainless steels possess a ferrite micro-structure like carbon steel, which is a body-centered cubic crystal structure, and contain between 10.6% and 27.2% chromium with very little or no nickel. They are magnetic.

This micro-structure is present at all temperatures due to the chromium addition, so they are not hardened by heat treatment. They cannot be strengthened by cold work to the same degree as austenitic stainless steels.
