X2CRNBZR17
1 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
EN10088-1:2005, Table 2, cast/heat-analysis mass fractions wt%; complete Table 2 in the official SIST adoption preview PDF8; The preview is not the complete standard. ; Note a: unlisted elements must not be intentionally added without purchaser consent, except additions needed to finish the heat; A blank is not zero; no residual maximum is inserted without a source. ; Note b applies only to grades marked b; S must be checked separately for the selected product and property conditions and is not extended to the entire table. ; The coupled minimum for Ti/Nb/Zr and C/N is retained separately; no N maximum is provided in the table, and this is not entered as zero; The corresponding coupled condition cannot be confirmed without measured N. ; This part is a stainless steel designation list; specific delivery and mechanical-property requirements must follow the corresponding product standard; Cold-heading suitability, supply or equivalence between national editions is not established. ; Zr≥7(C+N)+.15; No independent maximum
