Stainless Steels

They fall into four categories (with some overlap)

Martensitic stainless steels ranges from a wide variety of properties and are used as stainless engineering steels, stainless tool steels, and creep-resistant steels. They are magnetic, and are not as corrosion-resistant as ferritic and austenitic stainless steels due to their low chromium content.

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).

Resistance To Ferric Oxide Formation

Stainless steel's resistance to ferric oxide formation results from the presence of chromium in the alloy, which forms a passive film that would protect the underlying material from corrosion, and can self-heal in the presence of oxygen. Corrosion resistance can be enhanced further, by:

addition of molybdenum (which also improves resistance to "pitting corrosion")

increasing the chromium content to levels above 11%;

addition of 8% or higher amounts of nickel
