Review of Australian Standards. To keep abreast
9、of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto. Full deta
10、ils of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine The Australian Standard, which subscribing members receive, and which gives details of new publications, new editio
11、ns and amendments, and of withdrawn Standards. Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standard should be made without delay in order that the matter ma
12、y be investigated and appropriate action taken. This Standard was issued in draft form for comment as DR 94109.

13、RALIA) 1 THE CRESCENT, HOMEBUSH, NSW 2140 ISBN 0 7262 9556 6 Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 06 Mar 2008 AS 154819952 PREFACE This Standard was prepared by the Standards Australia/Standards New Zealand Committee ME/1 on Pressure Equipment and supersedes AS 15481988, Steel plates for boi
14、lers and pressure vessels. This Standard is the main material Standard referenced in AS/NZS 1200, Pressure Equipment. AS/NZS 1200 is the main Australia/New Zealand Standard for pressure equipment which outlines the general requirements for shell boilers, water-tube boilers, pressure vessels, pressur
15、e piping, welder certification and related matters. In this edition, the concept of interchangeability has been extended to 7 490R and 7490RH grade plates. The Standard covers both continuous casting and ingot casting steelmaking practices. A niobium addition of up to a maximum of 0.025 percent is p
16、ermitted to Type 7 steels (L20 and below) in order to achieve good low temperature properties without affecting the weldability of steel plates. However, the addition of niobium is not permitted to R, RH, A and AH designation for Type 7 grades, thus not affecting its interchangeability as specified
17、in Appendix C. The impact energy values on RLO grades have been increased to bring them in line with those specified in AS 1210, Unfired Pressure Vessels (known as the SAA Unfired Pressure Vessels Code). Impact tests in the transverse direction have not been made the base impact test requirement, as
18、 this is a rare requirement. As well, there are no provisions for transverse impact tests in AS 1210. The verification option and the former Appendix C, which gave charts for verification of elevated temperature proof stress, has been deleted from this Standard. This aligns with ISO 9328-21991, Stee
19、l plates and strips for pressure purposesTechnical delivery conditions, Part 2: Unalloyed and low-alloyed steels with specified room temperature and elevated temperature properties and EN 10028-21992, Flat products made from steel forpressurepurposes,Part 2: Non-alloyandalloysteelswithspecifiedeleva
20、ted temperature properties. A provision has been made to supply plates to three levels of reduction of area requirement in a through-thickness direction. A new Clause A6 has been added for distributors or users to carry out any additional testing on base grade (e.g. elevated temperature test or impa
21、ct test) without necessarily having to carry out the stress-relieving treatment. Appendix D, Creep Rupture Properties, has been updated and aligned with ISO 9328-2 and EN 10028-2. In so doing, additional creep values for 10 000 hours and 250 000 hours are added. ISO/EN Standards do not give creep va
22、lues for Type 5 (niobium bearing) steels. The 5-490 creep values are based on either historical data or calculated as 95% of 7-430/7-460 grades. As a result, these values are lowered in some cases. The term informative has been used in this Standard to define the application of the appendix to which
23、 it applies. An informative appendix is only for information and guidance.
