Comparison of the forming behavior of DD14, DD14 Ti and DD14 Bor on the basis of the forming limit curve (example)
Steel grade DD14 Bor offers a low yield strength and high elongation values. Due to its particularly good forming properties, this steel meets the requirements for the most complex of components.
