AS/NZS 1594:1997 pdf free.Hot-rolled steel flat products.
1.1 SCOPE 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)
1.3 DEFINITIONS For the purpose of this Standard, the definitions below apply.
1.3.1 Ageing-a term applied to changes in mechanical properties of low carbon steel which occur with the passage of time, and which adversely affect formability. Ageing accelerates as the temperature is raised.
1.3.2 Cast analysis-a chemical analysis determined on a test sample taken during the casting of the liquid steel.
1.3.3 Edge conditions
1. 3.3.1 Trimmed edge-the resulting edge produced by the removal of material by mechanical means or gas cutting: also referred to as sheared edge or slit edge.
1. 3.3.2 Untrimmed edge-the edge produced by rolling between horizontal rolls, with or without vertical edging rolls: also referred to as mill or universal edge.
1.3.4 Floorplate-a hot-rolled product supplied in cut lengths or in coils, having a rolled raised pattern, at regular intervals, on one surface, with a minimum width of 600 mm and a nominal minimum thickness of 2 mm. Its edges may be either trimmed or untrimmed.
1.3.5 Hot-rolled sheet-a hot-rolled product supplied in cut lengths and produced by cutting from a coil rolled on a continuous mill. It has a width of a least 600 mm and a nominal thickness of less than 3 mm. The edges of the sheet may be either trimmed or untrimmed.
1.3.6 Longitudinal direction-the direction of greatest extension of the steel during rolling.
