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".

Grade 1004 steel, which is a low-carbon steel, typically has a hardness in the range of 120 to 156 Brinell hardness (HB) depending on its specific heat treatment and processing. Its low carbon content contributes to its ductility and machinability, making it suitable for various applications. For precise hardness values, it's essential to refer to the specific manufacturer's specifications or standards.
the main reason might be that the percentage of carbon increase the hardness of material (steel ) and ductility would decrease
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.
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.
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.
The main alloy in steel that determines its hardness is carbon. The carbon content in steel affects its strength and hardness by influencing the formation of different microstructures during the cooling process. Higher carbon content typically results in increased hardness.
Hardness - when carbon is added to steel, the hardness is increased

Carbon is the main hardening element in steel. However, increasing the hardness decreases the ductility. Strength in this case is relative.
The carbon content in stainless steel affects its hardness, strength, and corrosion resistance. Higher carbon content can increase hardness and strength but may reduce corrosion resistance. Lower carbon content can improve corrosion resistance but may decrease hardness and strength. Balancing carbon content is crucial in determining the overall properties of stainless steel.
Yes, 1018 steel is prone to rusting as it contains relatively low amounts of carbon, making it more susceptible to corrosion compared to other steels. To prevent rusting, it is important to properly clean and protect the surface of the steel with coatings or treatments.
