Influence of Deformation and Quenching Temperature on Structures and Properties of High Nitrogen Stainless Bearing Steel
The influence of deformation and quenching temperature on microstructure and properties for high nitrogen stainless bearing steel was studied using the calculation of Thermo-Calc software and relevant Fe-based database and some experiments.The results showed that there was a small precipitation amount of carbide in the sample after a large deformation.The value of impact toughness (AKU) was increased from 2.0 J to 12.0 J with the deformation increasing from 71% to 83%.When the quenching temperature reached 1050℃,the value of the hardness was up to the tiptop.Additionally,according to the calculation,it was found that there was a linear functional relation between the precipitation of carbide M23C6 (M) and quenching temperature (T).And the relational model could be expressed as: MM23C6=55.34-0.05T (T≥1000℃).
