Carbon Steel Wire Rod AISI 1018
Cost-effectiveness: Carbon steel wire rod composition (carbon content 0.15%-0.20%) reduces the difficulty of smelting, and the price is lower than that of medium and high carbon steel, which is suitable for bulk purchase.
Process friendliness: High plasticity (elongation ≥15%) supports secondary processing such as cold heading, drawing, welding, etc., reducing equipment loss.
Balance of strength and toughness: Tensile strength of 440-550MPa, meeting the standards for general mechanical parts.
International certification guarantee: Complies with ASTM standards, and provides material certificates and third-party test reports.
