2 brand representation
Flat steel grades are indicated by steel grades and cross-section dimensions, such as Q215-120×198. Q195 - carbon structural steel grade, 120 × 198 - the sectional size of the cathode flat steel.
3 Size, shape, weight and allowable deviation
3.1 Flat steel length and its allowable deviation
The cathode flat steel is delivered according to a fixed length, the length of the fixed length shall be specified in the contract, and its allowable length deviation is 0 to +15 mm.
3.2 The four corners along the length of flat steel, the arc radius 5mm ~ 15mm.
3.3 After consultation between the supplier and the buyer, special specifications and requirements are ordered according to the agreement between the supplier and the buyer.
Cathode flat steel is delivered according to actual weight. After negotiations between supply and demand sides, they can also be delivered according to theoretical weight. Flat steel measurements are calculated according to nominal dimensions and the specific gravity is calculated at 7.85t/m3.
4 Technical Requirements
4.1 Chemical composition
4.1.1 The chemical composition of the flat steel (smelting analysis) shall comply with the provisions of Table 6.
4.1.2 After negotiations between the supplier and the buyer, other brands than GB/T 700 may also be used, and they must be specified in the contract.
The allowable deviation of the finished chemical composition of the flat steel shall comply with the provisions of GB/T 222.

4.2 Mechanical properties
The mechanical properties do not serve as delivery conditions for the cathode flat steel.
4.3 Method of manufacture
Flat steel raw material is smelted by Oxygen converter of 40T or more
4.3.2 Roll Forming
It is rolled into rectangular strip or thick steel plate by hot rolling and then processed into rectangular flat steel according to the required size by sawing or flame cutting.
4.4 Surface quality
The surface of the flat steel must not have visible cracks, folds, scabs, inclusions, and pressed iron oxide skin. If the above defects must be removed along the length direction, the clearance depth shall be calculated from the actual size of the flat steel and shall not exceed half of the tolerance.
