008CR27MO
6 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Applicability and limitations
GB/T 20878—2007 tabulated chemical-composition mass fractions wt%; Values in parentheses are maximum permitted additions; conditional expressions require manual interpretation against the original text. Footnote b permits Ni ≤0.50 and Cu ≤0.20, but Ni+Cu must remain ≤0.50; The previous Mo maximum of 1.75 was incorrect. A material-database match does not guarantee cold-heading suitability, actual supply or finished-product strength. GB/T 20878—2007 is a historical edition; This record does not replace verification of the current standard, contract or material applicability.
