PACKAGE
8 steel strips + PE film + packing cloth composed by paper and woven + pallet
Raw material wire rod used for 7 wire PC Strand
Chemical Composition (%):
Designation | C | Si | Mn | P | S |
SWRH82B | 0.79~0.86 | 0.10~0.30 | 0.6~0.9 | ≤0.03 | ≤0.03 |
Mechanical properties (after wire rod aging period)
Designation | Tensile Strength,MPa | Area Reduction,Z/% |
SWRH82B | 1130-1280 | ≥30 |
The wire breaking rate of drawing and stranding (stranding) shall be low (generally less than 3 times per 100 tons)
Inclusion and surface
Designation | Inclusion type | Inclusion grade | Standard |
SWRH82B | A,C | ≤ Level 2 | GB/T24238-2009 or JIS G3506 |
B,D | ≤ Level 1.5 | GB/T24238-2009 or JIS G3506 |
Class A and C belongs to plastic inclusion, and Class B and D belong to brittle inclusion
The surface of the wire rod shall be smooth and free of such harmful defects as cracks, folds, ears, scars, delaminations and inclusions
Metallographic structure
Designation | Sorbitization rate,% | Total decarburized layer, mm | Grain size, grade |
SWRH82B | ≥85 | not more than 1.5% D | not less than 7 |
Gas
Designation | [O], ppm | [N], ppm |
SWRH82B | ≤25 | ≤60 |
[O] It is easy to form oxide inclusions, which affects the properties of steel;
[N] Brittle nitride inclusions (TiN, AlN) are easily formed with high N content, and the higher N content, the larger the size of nitride inclusions, thereby reducing the plastic toughness of steel.
Raw Material Supplier
We only use the raw material from ROCKCHECK and XINGTAI IRON& STEEL
