Abstract

PURPOSE: To obtain toughness over a specified strength by adding a prescribed amount each of C, Si, Mn, Cr, acid sol. Al, acid soln. N, etc. and regulating the wt. ratio between Al and N to a prescribed value.
CONSTITUTION: Steel products consisting of 0.25W0.45% C, 0.15W0.35% Si, 1W 1.9% Mn, ≤0.5% Cr, ≤0.04% P, ≤0.005% S, 0.025W0.08% acid sol. Al, 0.006W 0.02% acid sol. N and the balance Fe while making the ratio of Al/N 2W6 are refined. To the products may be added 0.001W0.008% Ca. A chain with superior toughness correspnding to ≥70kg/mm2 tensile strength is obtd. using the steel products.
