The strain hardening exponent (also called strain hardening index), noted as n, is a materials constant which is used in calculations for stress-strain behavior in work hardening.
In the formula σ = K ε n,
σ represents the applied stress on the material,
ε is the strain,
K is the strength coefficient.
The value of the strain hardening exponent lies between 0 and 1. A value of 0 means that a material is a perfectly plastic solid, while a value of 1 represents a 100% elastic solid. Most metals have an n value between 0.10 and 0.50.

“O Master, let me walk with Thee
In lowly paths of service free;
Tell me Thy secret, help me bear
The strain of toil, the fret of care.”
—Washington Gladden (18361918)
“With sixty staring me in the face, I have developed inflammation of the sentence structure and definite hardening of the paragraphs.”
