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.
