Specifies requirements for the production and supply of hot-rolled structural steel plates and floorplates for carbon and carbon-manganese mechanically-tested steels, fully-killed analysis-only steels, and low-alloy (weathering) mechanically-tested steels.

This Standard specifies requirements for the production and supply of hot-rolled structural steel plates and floorplates for carbon and carbon-manganese mechanically-tested steels, fully-killed analysis-only steels, and low-alloy (weathering) mechanically-tested steels. This Standard also specifies requirements for the production and supply of wide slabs as fully-killed analysis-only steel. For general structural and engineering applications, all grades specified in this Standard are suitable for – (a) welding in accordance with AS/NZS 1554; or (b) riveting and bolting as specified in AS/NZS 4600, AS 3990, AS 4100 and NZS 3404.1. This Standard does not cover the following: (i) Structural steel – Hot-rolled bars and sections (AS/NZS 3679.1), and welded I sections (AS/NZS 3679.2). (ii) Steel plates for pressure equipment (AS 1548).(iii) Structural steel hollow sections (AS/NZS 1163). (iv) Hot-rolled steel flat products (AS 1594). (v) Structural and pressure vessel steel - Quenched and tempered plate (AS 3597). Means for demonstrating compliance with this Standard are specified in Appendix B. NOTES: 1 Guidelines to purchasers on requirements that should be specified by the purchaser and those that should or may be agreed on at the time of enquiry and ordering are given in Appendix A. 2 Guidelines on cold-bending and hot-forming of plate during fabrication are given in Appendix C
