This document replaces GB/T 24733-2009 "Austempered Ductile Iron Castings". Compared with GB/T 24733-2009, except for structural adjustments In addition to editorial changes, the main technical changes are as follows. a) Added terms and definitions (see 3.3, 3.5); b) Added one grade, QTD1600-1, and changed the yield strength of three grades, QTD800, QTD900 and QTD1050. The elongation after break of each grade has been changed (see Table 1, Table 1 of the.2009 version); c) Added side-by-side test blocks (see 7.2.2); d) Changed the composition of the sampling batch (see 10.1, 8.2 of the.2009 version); e) Added a normative appendix "Steps for cutting specimens" (see Appendix G). This document is drafted with reference to ISO 17804.2020 "Classification of Cast Austellite Ductile Iron", and the degree of consistency is non-equivalent.
