Alloy round steel is an industrial material with high hardenability, no temper brittleness, fairly good weldability, little tendency to form cold cracks, good machinability and cold strain plasticity. Standard: GB/T JIS ASTM A29M ISO

Carbon steel according to the chemical composition (i.e. to the carbon content) can be divided into low carbon steel, medium carbon steel and high carbon steel Low carbon steel: also known as soft steel, carbon content from 0.10% to 0.30% low carbon
