Abstract
Elongation to fracture values higher than 300% were obtained for cold
rolled AISI 304 type steel grades in hot tensile tests. The effects of
heating rate and carbon content on the elongation of the steels studied
are discussed based on internal friction measurements and TEM
observations. A slow heating rate to the test temperature and high
carbon content of the steel led to a fine and equiaxial grain structure
of the steels.
