The invention discloses steel for joints in an automobile drive system and a production method for the same. The steel comprises the ingredients, by weight, including 0.53%-0.57% of C, 0.22%-0.32% ofSi, 0.80%-0.95% of Mn, 0.20%-0.30% of Cr, no more than 0.010% of S, no more than 0.015% of P, no more than 0.0015% of [O], no more than 0.00015% of [H] and Fe. According to the ingredients, the steelfor the joints in the automobile drive system and the production method for the same disclosed by the invention are characterized in that material hardenability is obviously enhanced through adjustment and increase of the content of Mn and addition of Cr, so thermal processing technological performance of the material is improved; and the material hardenability is obviously enhanced in comparisonwith steel materials used conventionally under a same thermal processing technology (with a normalizing temperature of 870 DEG C and an end quenching temperature of 845 DEG C).
