why is Cold Drawn Steel stronger?

Do you feel Cold Drawn Steel Bar stronger than Hot Rolled Steel Bar or peeled, turned Bright Steel Bar? cold drawn steel bar is stronger because the tensile strength, yield strength and hardness are higher than hot rolled steel bar. Steel bar through cold drawing can not only change the diameters, surface, but also change the mechanical properties. Because cold draw steel bar is produced bu cold drawing through a mound, during drawing, the steel bar is squeezed to change the shape or size, so the hardness is higher and you feel steel bar is stronger.

Is steel bar stronger better than steel bar softer? That depends on your usage. For example, if you produce high strength components, then stronger steel bar is better. But if you want them easy maching, lower hardness steel bar is better.

Is there steel bar with higher strength and lower hardness, good elongation? Yes, heat treated steel bar can solve all problems to supply you most suitable usage.
