In order to meet market demand and diversify the product structure, based on the requirement on properties of high strength, high plasticity, good cold forging ability and easy drawing, study was carried on for the chemical composition, heating system and controlled rolling and cooling process of wire rod. Hot rolled wire rod produced by SWRCH35K cold heading steel was successfully developed. Production practice indicated its mechanical properties, metallographic structure, surface quality and cold forging property all met the requirements by the standard and the production requirements of the customer.
