Rockwell Hardness Testing of Steel Reinforcing Bar to

A procedure is described for performing Rockwell hardness testing of steel bar used for concrete reinforcement to obtain estimates of tensile strength. Analysis of the measurements was performed to assess the variation in hardness that exists in the bar. An estimate of its corresponding tensile strength resulted using a strength hardness

1018 vs A 36 steels, and CR vs HR Reference Materials

Sep 01, 2018 · A36Introduction ASTM A36 is the most commonly used mild and hot rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018.
