Applicability and limitations
GB/T 20878—2007 historical version; The P column in the original text is printed as 0.300%; the numerical dispute remains unresolved. This row does not participate in automatic composition reverse-checks and cannot be used as a material selection limit. Other listed elements are transcribed from the original version.
Composition conditions
- Original GB/T 20878—2007 composition, mass fractions wt%; Values in parentheses are maximum permitted additions.
- In this row of scanned original Table 4, P is clearly printed as 0.300%, conflicting with the 0.030% commonly seen in comparable records. The printed value is retained and marked for checking against a second original; it must not be used as a final material-selection limit.
- This standard does not guarantee cold-heading suitability or actual supply.
Verification notes
Original GB/T 20878—2007, Table 4, item 129 prints 0.300% in the P column, conflicting with other transcriptions; The value is not used as a material-selection or composition reverse-matching limit, pending an official correction or verification against a second original.Source uncertainties and differences
- Element
- P
- Source 1
- Item 129 in Table 4 of the original 2007 scan is printed 0.300%
- Source 2
- Other transcriptions commonly give 0.030%; no official erratum or second original suitable for cross-checking has yet been obtained
- Review conclusion
- Retain the original printing and prohibit automatic composition reverse-lookup matching; Enable only after manual verification
