Methods for producing alloy tools

A method for producing alloy tools, comprising:

• providing a steel wire rod, wherein chemical compositions of the steel wire rod comprise, by weight percentage:
• [C] 0.88%-0.92%, [Si] 2.31%-2.60%, [Mn] 0.40%-0.80%, [Cr] 0.70%-1.05%, [Ni] 1.31%-1.61%, [V] 0.14%-0.30%, [Al] 0.025%-0.060%, [P]≤0.025%, [S]≤0.020%, with the rest being Fe and unavoidable impurities, and the chemical compositions of the steel wire rod does not comprise [Mo] element;
• a fatigue life of the steel wire rod is not less than 30,000 cycles and an impact resistance of the steel wire rod is not less than 60 seconds;
• producing the alloy tools by using the steel wire rod, comprising:
• obtaining the alloy tools by subjecting the steel wire rod to bainite isothermal quenching and tempering treatment, wherein an austenitizing temperature is 905° C., a salt bath quenching temperature is 305° C., and a tempering temperature is 285° C.;
• and
• the providing a steel wire rod comprising:
• trimming and heating rolled billet, wherein heating temperature is within a range of 1160° C.-1190° C.;
• producing a wire rod by roughing rolling, intermediate rolling, pre-finishing rolling, and finishing rolling the rolled billet, wherein a finishing rolling temperature of the finishing rolling is within a range of 910° C.-950° C., and an exit temperature of a finishing mill used for the finishing rolling is not less than 970° C.;
• and
• producing the steel wire rod by cooling the wire rod, comprising:
• spheroidizing annealing the steel wire rod, wherein an annealing temperature is 765° C. and an annealing time is 12 hours.
