Steels supplied in either the cold-drawn or cold-rolled condition and which have not received a subsequent heat treatment shall comply with the chemical composition and mechanical propertics specified in Table 5 and Table 6. Steels in all other conditions shall comply with the chemical composition and mechanical propertics specified in Table 7.
The method of sampling for chemical analysis shall be in accordance with AS/NZS 1050.1. Chemical composition shall be determined by any procedures which are not less accurate than those given in AS/NZS 1050.1.
Wherever possible a chemical analysis of the steel from each cast shall be made to determine the proportions of the specified elements. In cases where it is impracticable to obtain samples from liquid steel, analysis of test samples taken in accordance with the requirements of AS/NZS 1050.1 may be reported as cast analysis.
The reported cast analysis of the steel shall conform to the requirements of Tables 1, 2, 3 and 4 for the appropriate grade.
For grades of steel excluding those designated ‘U’ or ‘M’, with prior hot-rolled cross-sectional areas up to and including 0.06 m’, the results of individual determinations carried out on the product shall be within the product analysis tolerance limits specified in Table 5.Where several determinations of a single clement, excluding lead, are carried out on products from any one cast, the spread of individual results shall not extend both above and below the range specified in Tables 1, 3 and 4.
Steel bars shall meet the following dimensional tolerance requirements:
(a) Tolerances for cross-sectional dimensions The tolerances for cross-sectional dimensions of round, square, hexagonal and flat bars shall be graded in accordance with Table 8 and shall conform to the limits given in Table 9.
(b) Tolerances for length With the exception of coils, the length of all bars shall be between 3 m and 7 m. They shall conform to the requirements of the mill length or the set length categories of Table 10.
NOTE: Bars may be in the cropped, saw-cut or chamfered form.AS 1443 pdf free download.
