Does anyone know which standard this steel belongs to and what its grade is?

If one can remember this, that’s also quite impressive

It’s not available in 20878 anyway, nor in any other commonly used materials

This is actually chromium-molybdenum steel, which belongs to the category of heat-resistant steels; a similar grade is 3Cr18Mn12Si2N. The standard applicable is GB/T 1221-2007 for heat-resistant steel bars.
