What is it about?
Warm working is the plastic deformation of metal at temperatures below the temperature range for recrystallization and above the room temperature. In this investigation, 1.0mm thick circular specimen of stainless steel AISI 304 were warm deep drawn and the influence of temperature on the deformation behaviour of material and the drawing loads which is required to draw the component was studied. The results show that the warm working has positive effects like reduced drawing load, negligible amount of increase in thinning and thickening of a drawn component when compared to the conventional drawing and also there is no necking or cracking occurs due to the temperature influence

Why is it important?
Even though, stainless steel has good formability characteristics, it is often difficult to deep draw in room temperature. This research work is carried out in warm condition to improve the forming.
Perspectives
This work is useful for improving forming capabilities especially in aeronautics,automobile, biomedical industries
