Beschreibung
Zusammenfassung:	Disclosed are a steel material for a solid stabilizer with high bendability, high hardenability and high quenching crack resistance, a solid stabilizer with high strength and a method for producing the solid stabilizer. The steel material for the solid stabilizer contains 0.24 - 0.40% C, 0.15 - 0.40% Si, 0.50 - 1.20% Mn, 0.03% or less P, 0.30% or less Cr, 0.01 - 0.03% Ti and 0.0010 - 0.0030% B by mass. The steel material for the solid stabilizer satisfies the conditions of formula (1). The diametrical center hardness of the steel material for the solid stabilizer after tempering is 400 HV, and the martensite ratio of the diametrical center after tempering is 80% or higher. 1.24
