@Qiao Y. X sir can you please help at this

Congfeng Wu

Full austenitic stainless steel is non-magnetic, both N and Ni can increase the range of austenite. So this steel with high nitrogen and free Ni may have some content of ferrite. You can calculate the ratio of Cr equivalent and Ni equivalent, and then see it has ferrite or not.

Thank you sir
