Abstract： Using forging equipment such as fast forging machines and radial forging machines， diferent forging routecombinations areused toforge hotwork die steel H13underthesame working conditions，and comparison and analysis areconducted basedon each forging experiment data; During the direct forging process of aradial forging machine，the metal mainlyflows inthe axial direction，andthecore forging permeabilityis poor，resulting in poor mechanical properties; When using afast forging and upsetting machine with adiameter forging machine for forming， the performanceoftheforgedmaterialissignificantlyimprovedintermsof tensilestrength，yieldstrength，elongation，poor transverse and longitudinal properties，and notch free impact energy.

Key words ： hot work mold steel H13; combination forging route; mechanical performance
