Differences between Cr5Mo, 0Cr5Mo, and 1Cr5Mo

I would like to ask the experts here: are Cr5Mo and 1Cr5Mo the same thing? I checked the textbook information: 0Cr5Mo indicates a carbon content of less than 0.1%, a Cr content of 5.5–6.49%, and a Mo content of less than 1.5%. Standard for metal content: Cr content
The notation for alloying elements in 1Cr18Ni9Ti, 0Cr18Ni9, and 00Cr18Ni18 is the same as that for low-alloy steels; the carbon content is expressed as a fraction of a thousand (represented by a single digit), denoted by C
High-carbon type: C > 0.15%, such as 2Cr13, 3Cr13, etc. Medium carbon type: 0.08% < C ≤ 0.15%, such as 1Cr13, 1Cr18Ni9, etc. Low-carbon type: 0.03% < C ≤ 0.08%, such as 0Cr13, 0Cr18Ni9, etc. Ultra-low carbon grade: C≤0.03%, such as 00Cr19Ni10, 00Cr17Ni14Mo2, etc
The three types of materials mentioned by the original poster are chromium-molybdenum steels with different carbon contents.
Scaring all the heroes here, learn *ji!
Impressive. . . . . . . . . . !
In which standard can the corresponding grades be found: Cr5Mo, 1Cr5Mo,
