摘要
采用10kg中频真空感应炉(ZG-0.01)冶炼不同N、Ni含量的06Cr19Ni10不锈钢,研究增N降Ni对06Cr19Ni10不锈钢组织和力学性能的影响。结果表明,当N含量在0～0.28%、Ni含量在5.98%～9.63%之间时,其显微组织仍为单一奥氏体,且其晶粒尺寸随着N含量的增大而降低,但恶化了其冲击韧度,室温冲击吸收功从N含量为0时的267J降低到N含量为0.28%时的228J;洛氏硬度、抗拉强度和屈服强度均随N含量的增大而提高;N含量为0.28%时,06Cr19Ni10不锈钢具有最优的力学性能,洛氏硬度(HRB)为95.4、抗拉强度为814MPa、屈服强度为437MPa、伸长率为52.5%。
The 06Cr19Ni10 stainless steel with different nitrogen and nickel content was smelted using vacuum induction furnace（ZG-0.01）to understand effects of increasing nitrogen and reducing nickel on microstructure and mechanical properties.The results show that microstructure of the test steel with nitrogen content of 0～0.28% and nickel content of 5.98%～9.63% keeps still the single austenitic,and the grain size is decreased with the nitrogen content increase,while the impact toughness of the test steel is deteriorated,where the room temperature impact absorption energy is reduced from 267 Jat the nitrogen content of 0 to 228 Jat the nitrogen content of 0.28%.Rockwell hardness,tensile strength and yield strength of the test steel are increased with the increase of nitrogen content.When the nitrogen content is 0.28%,the desirable mechanical properties of 06Cr19Ni10 steel are presented,where the Rockwell hardness,tensile strength,yield strength and elongation after fracture reach 95.4 HRB,814 MPa,437 MPa,52.5%,respectively.
