Surface Treatment Of Cold Rolled Coil
|
Surface Treatment |
Feature |
|
Chemical Treatment |
minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
|
retain the bright metallic luster for a long period |
|
|
Oil |
minimize the tendency for humid-storage stain |
|
Chemical Treatment and Oil |
The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
|
Dry |
must be transported and stored with special precautions to preserve low-humidity conditions. |
|
Anti-finger print |
minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
Application Of Cold Rolled Coil
|
Application |
Features |
Steel grades for example |
|
Commercial purposes |
With some ductibility, they are suitable to simple forming, bending or welding |
DC01, SPCC, St12 |
|
Drawing |
With more ductibility than the common ones, they are suitable to manufacturing parts through drawing and relatively complicated deforming |
DC03, SPCD, St13 |
|
Deep drawing |
With more ductibility and homogeneity than the drawing ones, they are suitable to manufacturing parts through deep drawing and complicated deforming. |
DC04,SPCE,St14 |
|
Extra-deep drawing |
With more ductibility and homogeneity than the deep drawing ones, they are suitable to manufacturing parts through extra-deep drawing and more complicated deforming. |
DC05, SPCF, St 15 |
|
Supreme extra-deep drawing |
With more excellent drawing capability than the extra-deep drawing ones, they are suitable to manufacturing parts through supreme extra-deep drawing and extremely complicated deforming. |
DC06, SPCG, St16 |
Features Of Cold Rolled Coil
1. Resistance to Corrosion Has better performance in corrosion resistance than hot dip galvanized coil/sheet of the same thickness and its service life is 1-5 times longer than general hot dip galvanized coil/sheet.
2. Machinability Can satisfy the processing requirements of rolling, coiling and others processes alike.
3. Thermal Resistance Can sustain the environment at 315°C for long time.
4. High Reflectivity Reflection ability of heat and light is twice as much as those of hot dip galvanized steel coil/sheet, and its reflectivity is more than 0.75, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction material of saving energy.
