HIGH-DRAWABILITY STEEL WIRE WITH A PROPORTION BY MASS OF CARBON OF A VALUE WHICH IS GREATER THAN OR EQUAL TO 0.6 % AND LESS THAN OR EQUAL TO 0.74 %

摘要

The invention concerns steel wire of a diameter d expressed in millimetres and having a proportion by mass of carbon C, expressed as a percentage, such that 0.6 % <= C <= 0.74 % and a maximum tensile strength R, expressed in MPa, such that when d < 0.17, R>= A.(920.C + 500)/d1/2 in which A=0.96, and when 0.17 < d < 0.23, R>= A. (920.C + 500)/d1/2 in which A= 1.24.
