Specifies requirements for hot-rolled steel plate, floorplate, sheet and strip rolled on a continuous mill, in thicknesses up to 8 mm for formability and extra formability grades, and up to 16 mm for other grades. It also specifies requirements for analysis, structural, weather-resistant and floorplate grades, and for widths up to 2000 mm. It includes slit material, provided that the parent metal has an as-rolled width of not less than 600 mm.

This Standard specifies requirements for hot-rolled steel plate, floorplate, sheet and strip, rolled on a continuous mill, in thicknesses up to 8 mm for formability and extra formability grades and up to 16 mm for other grades, and for widths up to 2000 mm. It includes slit material, provided that the parent material has an as-rolled width of not less than 600 mm. The Standard specifies the following grade requirements:(a) For analysis grades -chemical composition only.(b) For formability grades, extra formability grades, and structural grades including weather-resistant grades - both chemical composition and mechanical properties.(c) For floorplate -both chemical composition and mechanical properties.The Standard permits the addition of boron and micro-alloying elements for the achievement of special properties.NOTES:This Standard does not cover the following:(a) Steel plate for boilers and pressure vessels (see AS 1548).(b) Hot-rolled structural steel plates, floorplates and slabs (see AS/NZS 3678).Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.Alternative means for demonstrating compliance with this Standard are given in Appendix B.
