The stainless steel of this composition is really not common, I checked the metal material brand manual, the world steel brand manual and so on, searched for more than one hour but did not find the corresponding brand, may be the new brand or the new material.
Therefore, judging by the knowledge of steel I know, it is either Cr12Mn8 stainless steel or Cr12Mn9Si stainless steel.

The stainless steel of this composition is really not common. I checked the metal material grade manual, world steel grade manual, etc. and found no corresponding grade for more than one hour. It may be new grade or new material.

What is carbon 0.025, silicon 0.41, manganese 1.37, phosphorus 0.032, sulfur 0.001, chromium 18.36, nickel 8.27

Is not 304,0Cr8Ni9, stainless steel one.
