2507 Chemical composition of stainless steel:
C≤0.03, Si≤0.80, Mn≤1.2, Cr: 24-26, Ni: 6-8, S≤0.02, P≤0.035, Mo: 3-5, N: 0.24-0.32
2507 stainless steel in the appropriate solution treatment, the steel microstructure has an ideal α / γ ratio of about 50/50 biphase structure. When the solution temperature is above 1050 ℃, the amount of ferrite phase in the steel will increase with the increase of temperature, but the proportion of the ferrite phase in the steel will not change significantly when the nitrogen content is high. If this steel does not have different temperature aging (or the impact of heat), there will be γ2 formation on the α + γ matrix and the precipitation of δ, χ, R, α` intermetallic phase and Cr2N, etc., due to the carbon content in the steel Low (usually 0.01% -0.02%), so there is no carbide in the steel.
