Patent

CA 2164579

A lowly decarburizable spring steel comprises, on the weight basis, 0.40 to 0.70% of C, 0.15 to 2.50% of Si, 0.40 to 1.20% of Mn, 0.005 to 0.100% of Al, 0.005 to 0.050% of S, at least one of 0.05 to 2.50% of Ni and 0.05 to 1.00% of Cu, optionally further at least one of 0.20 to 1.50% of Cu, 0.05 to 1.00% of Mo, 0.01 to 0.50% of V, 0.010 to 0.300% of Nb and 0.0005 to 0.0050% of B, and the balance consisting of Fe and unavoidable impurities. The spring steel can be remarkably lowered in decarburizability during hot working and heat treatment thereof without need of any decarburization-proofing agents and any specific heat treatment equipment. Accordingly, it has a very excellent effect that decarburization thereof can be remarkably decreased with a low cost when it is applied to a coil spring, a flat spring or a torsion bar.
