Dear teachers, may I ask how to eliminate the discoloration that occurs after cutting stainless steel with plasma cutting?

If there are any good methods, please let me know. Thank you!
High-temperature plasma cutting inevitably causes oxidation; discoloration is unavoidable. Otherwise, machine machining should be used.
For small areas, grinding can be used; for larger areas, pickling can be employed.
