Room Temperature

In terms of mechanical properties, stainless steels can be roughly divided into four groups with similar properties within each group: martensitic and ferritic-martensitic, ferritic, ferritic-austenitic, austenitic. The difference in the mechanical properties of different stainless steels is perhaps seen most clearly in the stress-strain curves below.

Elevated Temperatures

At elevated temperatures the high temperature strength of various steel grades is illustrated by the yield strength and creep rupture strength curves below.
