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.

Applicable conditions and limitations

ASTM A193/A193M-26, Table 1: heat-analysis mass fractions in wt%; single values are maxima unless a range or minimum is stated. Ellipses indicate no requirement and are not entered as zero.

Intentional additions of Bi, Se, Te and Pb are prohibited; this does not mean that measured contents of these elements are zero.

Product-analysis tolerances in Table 1 are applied separately and are not added in advance to the heat-analysis ranges.

Only chemical composition has been checked in this record. Class, heat treatment, dimensions and inch-pound or metric properties require separate confirmation. This is not a guarantee of cold-heading suitability, finished-product properties or actual supply.

Dynamic stabilization minima must be checked jointly using C or C+N and Nb/Ti from the same analysis. Missing values are not replaced by zero, and the conditions are not converted into fixed minima.

The same original table row lists UNS S34751. This designation correspondence is retained only for this source; it does not establish verification of other standards or editions.
