Zusammenfassung:	PURPOSE:To produce inexpensively a product for cold forging by subjecting a specifically composed steel having an excellent strain aging resistance to a surface treatment by zinc phosphate, etc., then to a lubricating treatment, drawing and preforming the treated steel and subjecting the same to normal forming after another surface treatment and lubricating treatment. CONSTITUTION:The steel bar or wire consists of
