Effect of cold working on hardness and strength pProperties of 316 austenitic stainless steel

Abstract EN

The objective of this research was to study the effect of strain hardening on mechanical properties of 316 austenitic stainless steel (ASS).

Cold deformation was performed by using a universal tensile machine for 20 % CW and 40 % CW followed by heat treatment to relieve internal stresses.

A secondary cold working was performed for the heat-treated samples followed by a secondary heat treatment.

Rockwell hardness measurements and microscopic examinations were performed for all samples.

It was observed that by increasing the amount of CW %, both hardness and strength were increased.

On the other hand, the ductility was decreased.

The microstructure examinations showed an increase in the martensitic phase by increasing the cold working of the material.
