Approximate Minimum Mechanical Properties of Some Steels

Approximate Minimum Mechanical Properties of Some Steels
Hot Rolled – Cold Drawn – Annealed – Quenched & Tempered at 1000°F.
The following table represents an average of results obtained from a large number of tests and is offered only as a guide in accordance with standard procedure, the specimens used were 1” diameter.  Under no condition do we guarantee these statistics to be accurate.

The section size, finishing temperature and cooling rate during the rolling process influence the final mechanical properties of any steel in the As-Rolled condition.  The amount of size reduction in cold drawing will affect the mechanical properties of Cold Drawn Bars.  Turned and Polished as well as Turned, Ground & Polished Bars have approximately the same mechanical properties as the Hot Rolled Bars from which they were produced.
