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".

the main reason might be that the percentage of carbon increase the hardness of material (steel ) and ductility would decrease
* Mild (low carbon) steel: approximately 0.05-0.15% carbon content for low carbon steel and 0.16-0.29% carbon content for mild steel (e.g. AISI 1018 steel). Mild steel has a relatively low tensile strength, but it is cheap and malleable; surface hardness can be increased through carburizing. * Medium carbon steel: approximately 0.30-0.59% carbon content(e.g. AISI 1040 steel). Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components. * High carbon steel: approximately 0.6-0.99% carbon content. Very strong, used for springs and high-strength wires. * Ultra-high carbon steel: approximately 1.0-2.0% carbon content. Steels that can be tempered to great hardness. Used for special purposes like (non-industrial-purpose) knives, axles or punches. Most steels with more than 1.2% carbon content are made using powder metallurgy and usually fall in the category of high alloy carbon steels.
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.
