Stress-strain behaviour of carbon steel and stainless steel

The stress-strain behaviour of stainless steel differs from that of carbon steel in a number of respects. The most important difference is in the shape of the stress-strain curve. Whereas carbon steel typically exhibits linear elastic behaviour up to theyield strength and a plateau before strain hardening, stainless steel has a more rounded response with no well-defined yield strength

Comparison of structural behaviour of stainless steel and carbon steel members The main reasons for the difference instructural behaviour between carbon and stainless steel members are: 
The stress-strain curve for stainless steel departs from linearity at a much lower stress than that for carbon steels
Stainless steels have greater ductility and a greater capacity for work hardening than carbon steels
The material modulus of stainless steel reduces with increasing stress, unlike that of carbon steels which is constant
The residual stresses arising from fabrication are higher in stainless steel than in carbon steel.

As a result of this, different buckling curves are required from those of carbon steel. This applies to: 
local (plate) buckling for elements in compression
flexural, torsional, torsional-flexural buckling for members subject to axial compression
lateral-torsional buckling for beams with unrestrained compression flanges
