ABSTRACT:
Anti-vibration steel materials containing not more than 0.1% of carbon and not more than 0.5% of manganese and having an .alpha. value of not lower than 55, said value being a product of the yield point or stress at 0.2% strain and the grain size number, and a method for producing the same which comprises hot rolling a steel slab, billet or bloom containing not more than 0.1% of carbon, not more than 0.5% of manganese, giving not more than 10% of strain to the hot rolled steel, annealing the hot rolled steel thus strain given at a temperature not lower than its recrystallization temperature but not higher than its A.sub.3 transformation point for at least one minute and controlling the .alpha. value as defined herein to a value not more than 55.
