Processing Of Cold Rolled Steel Coils
The base material for cold rolled steel coils is hot rolled steel. We need to first make the production of full-hard cold rolled steel coils which is produced by rolling hot rolled steel. The surface of full-hard cold rolled steel coils is usually more smooth and bright than hot rolled steel. However, the internal stress of cold rolled steel coils is high and it’s very hard , not easy to bend. So we ususlly make the cold rolled steel coils soft and cancel the internal stress by annealing.
Standard Of Cold Rolled Steel Coils
The standard of cold rolled steel coils varies according to different countries, but which is major used as per EN,JIS,GB and DIN.
Steel Grade Of Cold Rolled Steel Coils
Standard of cold rolled steel coils as per EN 10130, then the steel grade of cold rolled steel coils can be DC01, DC02, DC03, DC04.
Standard of cold rolled steel coils as per GBT11253, then the steel grade of cold rolled steel coils can be Q195,Q235.
Standard of cold rolled steel coils as per JIS G3141, then the steel grade of cold rolled steel coils can be SPCC,SPCD,SPCE.
Standard of cold rolled steel coils as per DIN 1623, then the steel grade of cold rolled steel coils can be ST12, ST13, ST14, ST15
Different steel grade of cold rolled steel coils means different drawing quality.
Surface Treatment Of Cold Rolled Steel Coils
Usually, the cold rolled steel coils are oiled to protect the cold rolled steel coils against corrosion during the storage or transportation.
Surface Finish Of Cold Rolled Steel Coils
Usually, the surface of cold rolled steel coils can be bright,semi-bright, normal and rough. And sometimes, our clients also need the cold rolled steel coils with black annealed. So the surface is black due to the oxidation of steel in the air.
Applications Of Cold Rolled Steel Coils
Cold Rolled Steel Coils is used in a very wide range, mainly used in automotive, appliance, machinery, printing, construction, building materials, bicycles and other industries, production of organic coated steel is also the best selection.
