Another important factor when testing steel is the Yield or Elastic strength. This is the point at which the Stretched steel does not rebound to its original position or the point of a Bulge. This point cannot be simply taken as a given percentage of the Ultimate Tensile strength as some alloys have a yield of a higher percentage then do others.

As a general rule, Damascus & Low Carbon steels will have a lower yield point in relation to their ultimate than will higher alloy steels. This was how the thought was started that Damascus was better than steel because it would bulge while steel would burst. In reality, it only proved that Damascus had a lower yield strength than did the steel.
