Research on Decarburization Sensitivity of High Aluminum Steel 38CrMoAl
In order to study the decarburization sensitivity of high-aluminum steel 38CrMoAl,solve the problem of decarbonization in actual production,the test compared the decarburization of three steel grades at 980 ℃ 1 hour,air cooling and water cooling to room temperature and high aluminum steel at different temperatures of 780～980 ℃ after 1 hour.The results show that the non-carbide-forming element aluminum in steel can significantly increase the activity of carbon in steel,which increases the decarburization sensitivity of steel.Water cooling reduces high temperature times and reduces decarburization.Heating in the temperature range of 830 ℃～980 ℃,the total decarburization in steel does not change much,and the reduction of temperature in actual production does not improve decarbonization much.
