Explanation

Adding trace (no more than 0.2%, usually less than 0.1%) special alloy elements (such as niobium, vanadium, titanium, boron, etc.) to steel is called. The main functions of the micro alloy carbonitrides are: high temperature insoluble micro alloy carbonitrides prevent austenite grain growth, strain induced precipitation micro alloy carbonitrides prevent recrystallization grain growth, solid solution micro alloy elements and strain induced precipitation micro alloy carbonitrides strongly regulate deformation austenite recrystallization behavior The strain induced precipitation and the nanometer sized microalloyed carbonitride precipitated in the ferrite precipitation produce a strong precipitation strengthening effect and fix the carbon and nitrogen elements in steel. The good combination with controlled dairy technology can significantly improve the performance of steel product, which is one of the most important development directions of modern iron and steel industry.
