Study on Effect of Pressure to Nitrogen Solubility Limit in High Nitrogen Steels

Abstract:

This paper aims to study the effect of time and pressure on the nitrogen solubility limit through single factor experiment. The experiment is operated in the independent designed device whose main part is high temperature and high pressure reactor, Using high pressure and bottom blowing nitrogen in the furnace, it can gain high nitrogen nickel-free stainless steels whose nitrogen content is more than 1.1%.;The results show that there is solubility limit of nitrogen in 18Mn18CrN steel under certain condition ; The solubility limit of nitrogen in steel increases with the growth of pressure which ranges from 0.4MPa to 1.4MPa.
