Applicability and limitations
Clause 6.1.1 of GB/T5953.1/.2:2009 follows the relevant standards identified in the contract; This is reference composition for the same designation under GB/T6478; the applicable standard must be confirmed by contract, and these values are not directly treated as mandatory composition under 5953. Historical data from an earlier edition. No edition is stated on the website; Displayed under this source edition; contract applicability is not established

Applicability and limitations
GB/T6478-2001, Table 2, heat analysis wt%; 6.1.4 residual Cr/Ni/Cu are each ≤.20%; alloy Cr ranges are not subject to the residual maximum. ; 6.1.8 product-analysis tolerances require separate verification under GB/T222-1984, Table 2, and do not widen the default heat-analysis range. ; Actual 2001 edition; Composition from editions 2015 or 2025 is not substituted for this edition; specific dimensions and delivery mechanical properties require separate verification.
