Rockwell Hardness of steel 1018 ranges from 71 to 78 converted from Brinell hardness. The difference from 71 to 78 is caused by manufacturing metods and/or purity of the alloy.
The corresponding test for 1018 is RHB wich must be done using 1/16 a ball penetrator.

In a lab experiment, I found the hardness of a sample of C-1018 Annealed carbon steel to be 73.58 (averaged over 6 runs) on the HRB scale.

1018 is the number "one thousand and eighteen."It is also the name for 1018 steel which is the most common low-carbon mild steel alloy in many uses, including structural steel.

Between 121-137 on the Brinell hardness scale - which is quite soft. The end parts are generally case-hardened before use to 60+ Rockwell "C".
