| Abstract: | There is a relationship between the steel bar Leeb hardness and its tensile strength. In this paper, through plentiful experiments, the factors that affect steel bar Leeb hardness were investigated and the test conditions was set up for the on site test, so as to establish a special formula to perform a non-destructive testing on site. The measuring deviation is within 5%, so it has high application value. |

| Keywords: | Leeb hardness steel bar tensile strength non-destructive test |
