| Abstract: | Influences of acid soluble aluminum content and micro alloyed titanium on the grain coarsening tendency of austenite, hardenabilty and mechanical properties of 18CrMnB steel with higher nitrogen content have been studied and impacts of heating temperature on the content of boron in the solid solution and cooling rate on the distribution of boron in steel also investigated. The necessity for fixing the nitrogen in the steel 18CrMnB is deliberately expounded and appropriate fixing scheme for the steel determined. |
