| Abstract: | The effects of chemical elements in steel are analyzed, the properties, toughening mechanism of steel are described. The optimum heat treatment process is determined by researching the heat treatment process （cold treatment, aging） and mechanical properties. The research results showed that A100 alloy trial-produced by Changcheng Special Steel Co.,Ltd., had very high toughness and strength, which could get a best combination of toughness and strength through 885℃oil quenching plus-73℃cold treatment plus 480℃aging;A100 alloy must have high purity so as to guarantee the toughness and plasticity of the alloy. |
