Abstract

The present invention relates to a spring steel of high strength having excellent rolling properties of wire rod, consisting essentially of, in terms of% by mass: c: from 0.40% to 0.65%; yes: from 1.20% to 2.80%; mn: from 0.30% to 1.20%; p: 0.020% or less; s: 0.020% or less; cu: 0.40% or less; ni: 0.80% or less; cr: 0.70% or less; ti: from 0.060% to 0.140%; al: 0.10% or less; n: 0.010% or less; and o: 0.0015% or less, and optionally: b from 0.0005% to 0.0050% with the remainder being fe and unavoidable impurities, in which the content in% by mass of the specified chemical components meets the following expressions (1) to (3): X1 = 0.14 x [si] - 0.11 x [mn] - 0.05 x [cu] - 0.11 x [ni] - 0.03 x [cr] 0.02 <= 0.2. Expresiºn (1) X2 = (α - 500)/β > = 3.0 ... Expression (2) α = 912 - 231 x [c] 32 x [si] - 20 x [mn] - 40 x [cu] - 18 x [ni] β = 10 ^ (0.322 - 0.538 x [c] 0.018 x [si] 1.294 x [mn] 0.693 x [cu] X3 = 31 x [c] 2.3 x [si] 2.3 x [mn] 1.25 x [cu] 2.68 x [ni] 24,0 ...
