EA4T is a kind of low carbon high alloy steel of Germany brand. Through the composition analysis of this material,it was smelted out. The forging and heat treatment technology was studied and then the structure and me-chanical property were checked. The following processes were got,forging temperature was 1150 - 850℃,heat treat-ment technology: quenching + high temperature temper,quenching temperature was 900 - 920℃,and tempering tem-perature was 600 - 650℃. Under the processes metioned above,metallographic structure of temper sorbite and little temper bainite,satisfying mechanical property were obtaimecl.
