X3NICR18-16
2 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
ISO 4954:2018 Table D.2 gives cast analysis; single values are maxima and dashes are not zero.
Product-analysis deviations are listed separately under Tables 2/3, not used directly to relax cast-composition limits.
Elements not listed must not be intentionally added without the purchaser's consent, except for finishing the heat.
