Hot-rolled wide flat for construction
1 Scope
This standard specifies the terms and definitions, order content, dimensions,
shape, weight and allowable deviations, technical requirements, test methods,
inspection rules, packaging, markings and quality certificates of hot-rolled wide
flat steel for structural use.
This standard is applicable to strip-shaped wide flat steel which has a thickness
of 4 mm ~ 40 mm, a width of 150 mm ~ 600 mm, in a rectangular cross-section
for structural use, hot-rolled on all four sides.

3 Terms and definitions
The following terms and definitions apply to this standard:
3.1
Wide flat
Wide flat steel refers to a steel with a width greater than or equal to 150 mm
and a thickness usually greater than 4 mm, generally delivered in straight
bars, not in coils, with edges and corners on the sides. Wide flat steel is
obtained by hot rolling on four sides (or by box-shaped hole).
4 Order content
a) This standard number
When the wide flat steel is delivered according to the theoretical weight, the
nominal size shall be adopted for calculating the theoretical weight. The density
of carbon steel is 7.85 g/cm3. Other steel types shall be as specified in
accordance with the corresponding standards.
6 Technical requirements
6.1 Designation and chemical composition
The designation and chemical composition of steel shall meet the requirements
of GB/T 700 and GB/T 1591. The allowable deviation of the chemical
composition of the finished wide flat steel shall meet the requirements of GB/T
222.
6.2 Smelting method
Steel is smelted by converter or electric furnace.
6.3 Delivery status
Wide flat steel is delivered straight in hot rolled status.
6.4 Mechanical properties and process properties
The mechanical properties and process properties of wide flat steel shall meet
the requirements of GB/T 700 and GB/T 1591.
6.5 Surface quality
6.5.1 The surface of the wide flat steel shall not have defects such as scars,
cracks, folds, inclusions, blisters, oxide scales that are harmful to use. There
shall be no delamination of wide flat steel.
6.5.2 The surface of the wide flat steel is allowed to have local defects such as
thin oxide scale, rust, slight pitting and scratches that do not affect the use. The
unevenness shall not exceed half of the thickness tolerance of the wide flat
steel; meanwhile it shall ensure the allowable minimum thickness of wide flat
steel.
6.5.3 The surface defects of wide flat steel are allowed to be cleaned up. The
cleaning place shall be smooth and without edges and corners, meanwhile the
allowable minimum thickness of the wide flat steel shall be guaranteed.
However, welding repair or blockage is not allowed.
6.5.4 For edge cracks and other defects caused by rolling, the depth shall not
exceed half of the width tolerance of the wide flat steel, meanwhile the wide flat
steel shall not be made smaller than the nominal width.
