3.5 Cold-rolled and annealed coil
Flat product manufactured by cold-rolling and subsequent annealing of hot-rolled coil.
Cold-rolled coil is hot-rolled coil that has been subjected to a cold-rolling reduction of more than 15%. The coil shall have a subcritical annealing cycle that recrystallises the structure and forms new ferrite grains. The resulting properties are similar to hot-rolled coil.
3.6 Crack
Narrow line of’ fracture on the surface.
3.7 Defects
Surface discontinuities, including cracks, laps and seams, in the base material and
out-of-tolerance weld seams.
3.8 Factory production control
Operational techniques and all measures necessary to regulate and maintain the conformity
of the product to the requirements of’ the relevant product Standard.
3.9 Fine grained steels
Steels which have an austenitic grain size of number 6 or finer when tested in accordance with AS 1733. Generally, steels are considered fine grained without the need for testing when the total aluminium content is greater than 0.020%, or when niobium  0.0 1%, titanium  0.0 1% or vanadium  0.02% are deliberately added as carhonitride f’ormers.
NOTE: AS 1 733 includes various recognized methods for grain size determination, including the McQuaid-Ehn method, and appropriate etching techniques.
3.10 Heat
A product of a ladle of steel melted in one vessel and processed under the same conditions.
3.11 Hot-rolled coil
Flat product manufactured by hot-rolling semi-finished products.
Includes products that have been subjected to a light cold-rolling pass, normally less than 5% reduction, known as a ‘skin pass’.
3.12 Inspection
Judgement by competent personnel to determine acceptability against requirements.
3.13 Lap
Overlapping material partially connected with the base material.
3.14 Longitudinal direction
Direction parallel to the longitudinal weld seam.
3.15 Longitudinal weld seani
Continuous weld joining both edges of’ the single strip of steel used to form a hollow section.
3.20 Shall Indicates that a statement is mandatory.
3.21 Should Indicates a recommendation.
3.22 Structural hollow sections Tube intended to be used for structural purposes.
3.23 Supplier An organization or person that provides a steel products manufactured to this Standard.
3.24 Testing Chemical analysis tests and mechanical tests undertaken by an accredited laboratory as required by this Standard.AS 1163 pdf download.
