Microstructure of austenitic stainless steel after solution treatment
Thread Content
Is the microstructure of austenitic stainless steels such as 316L 100% austenitic after solution treatment? (Today, when using the magnetic method to determine the ferrite content, I placed the probe on a 316L plate, but there was no reaction at all.) I would appreciate it if someone could give me some guidance; it would be great if you could also recommend some relevant books or materials. Thank you very much~~~
I’m not sure if it’s possible to achieve 100% austenite; in our quality control processes, to ensure the pitting resistance of stainless steel, the ferrite content is kept within a range of 6%-9% at the lower limit
Generally, 316L material cannot achieve 100% austenite, as the 316L used in urea equipment is a modified version of 316L mod material, with a higher nickel content.
In fact, 100% cannot be achieved; temperature control cannot be fully theorized. It's just that austenite accounts for the largest proportion. Personal understanding
