I'm looking for some information on AISI 51XX steels, especially their mechanical properties after various heat treatments and/or mechanical processing (hot forging especially). I would really appreciate it if anyone would help me with this matter.
AISI 51XX steel with 0.80% - 1.05% chromium usually is quenched in oil to prevent crack formation. Quenching in oil doesn't provide high mechanical properties of steel. It can be quenched intensively in water flow to increase mechanical properties of material, decrease amount of cromium . Speed of water depends on size of steel component. According to our experience, chemical composition of chromium steels should be optimized and intensively quenched to increase significantly service life of steel components and decrease omount of chromium in steel.
I familiar with 0.8% C , 2% Cr and 0.4% Mo steel and I have conducted a lot of research about it. If you think my information about this steel is useful, do not hesitate to inform me.
