| description | The invention discloses a machining method used for alleviating end cracking of annealed high-hardenability steel and belongs to the technical field of high-hardenability steel treatment. The machining method is used for solving the technical problem of steel end cracking. According to the method, thermal straightening is performed after steel is annealed and taken out of a furnace, the straightening temperature is controlled at 200~250 DEG C, and the steel comprises the components including, by weight, 0.29~0.31% of C, 0.28~0.32% of Si, 0.93~0.97% of Mn, 1.13~1.17% of Cr, 0.22~0.25% of Mo, 0.05~0.08% of Ti, 0.015~0.025% of Al, 0~0.02% of P, 0~0.008% of S and the balance Fe. According to the machining method provided by the invention, the structural stress and internal stress are effectively reduced, the end cracking rate is 0% after the machining method is improved, and the machining method is used for high-hardenability steel machining.
