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.
