High-strength steel wire is mainly made of carbon steel or alloy steel, also known as high-tension steel wire, which is a steel wire material with excellent tensile strength. The carbon steel wire of this steel wire is 80# steel, and the carbon content is usually between 0.7% and 0.9%. When the carbon content of the steel wire is increased (>0.9%), its effect is the same as cold working and heat treatment, which can improve the strength and hardness of the steel wire.
