AS 2074-2003 Cast steels
1.1 SCOPE AND APPLICATION
1.1.1 Scope
This Standard specifies requirements for carbon, low alloy and high alloy cast steels.
NOTES:
1 Advice and recommendations on information for optional test requirements to be supplied by the purchaser at the time of enquiry or order are contained in Appendix A.
2 A summary of chemical composition and tensile properties of steels included in this Standard is given in Appendix B, which also provides guidance on the selection of grades for specific applications.
3 AS 2074 only specifies materials. AS 4738 specifies the other additional requirements of the casting (See Preface).
1.1.2 Application
Castings shall comply with the general requirements of Section 1 and with the specific requirements of Sections 2, 3 and 4, as follows:
(a) Carbon steel…………………………………………………………………………………Section 2.
(b) Low alloy steel …………………………………………………………………………….Section 3.
(c) High alloy steel…………………………………………………………………………….Section 4.
1.1.3 Other requirements
The castings shall comply with AS 4738.
NOTE: The purchaser should specify AS 2074 and AS 4738 on the purchase order.
