Cold drawing is the process of forcibly stretching steel bars under normal temperature conditions with a tensile stress exceeding the original yield point strength, causing plastic deformation and achieving the goal of improving the yield point strength and saving steel.Cold drawn steel has a wide range of applications, mainly in the fields of mechanical manufacturing, construction industry, automotive industry, railway transportation, shipbuilding, and petrochemicals.Cold drawn round steel, square steel, flat steel, hexagonal steel and steel have high precision and strength, suitable for application scenarios requiring higher performance.
