◆ Properties
Chemical properties:
The reference values for the chemical composition (melt analysis) of the steel are shown in the table.
| Grade | C | Mn | P | S | Alta |
| DC04 | ≤0.08 | ≤0.40 | ≤0.030 | ≤0.030 | ≥0.020 |
a For grades DC01, DC03 and DC04, Alt≥0.015 when C≤0.01. * %(Mass fraction) | |||||
Mechancal properties:
| Grade | Yield strengtha,b ReL或RP0.2/MPa | Tensile strength Rm/MPa | Elongation after breakc,d A80/% (L0=80mm,b=20mm) | r90 valueee | n90 valueee |
| DC04 | ≤210 | 270~350 | ≥38 | ≥1.6 | ≥0.18 |
a Rp0.2 is used when there is no obvious yielding, otherwise ReL is used. when the thickness is greater than 0.50 mm and not greater than 0.70 mm, the upper limit of yield strength can be increased by 20 MPa; when the thickness is not greater than 0.50 mm, the upper limit of yield strength can be increased by 40 MPa. b By mutual agreement of supply and demand, the lower limit of yield strength of DC01, DC03 and DC04 can be set to 140 MPa, the lower limit of yield strength of DC05 and DC06 can be set to 120 MPa, and the lower limit of yield strength of DC07 can be set to 100 MPa. c The specimen is a P6 specimen in GB/T 228, and the direction of the specimen is transverse. d When the thickness is greater than 0.50 mm and not greater than 0.70 mm, the minimum value of elongation after break can be reduced by 2% (absolute value); when the thickness is not greater than 0.50 mm, the minimum value of elongation after break can be reduced by 4% (absolute value). e The requirements of r90 value and n90 value only apply to products with thickness not less than 0.50 mm. When the thickness is greater than 2.0mm, the r90 value can be reduced by 0.2. | |||||
◆ Characteristic
DC04 steel coil is classified according to the maximum allowable yield strength, and its quality is suitable for high deformation requirements.
DC04 steel coil is a cold rolled low carbon steel with specific characteristics. It is known for its excellent formability, making it suitable for applications requiring complex shapes and precise bending.
Features of cold-rolled steel coil:
1. cold rolled steel coil thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.
2. The maximum thickness of cold-rolled steel coil is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel coil in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.
3. cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.
◆ Application
DC04 steel coil is a cold rolled low carbon steel with specific characteristics. It is known for its excellent formability, making it suitable for applications requiring complex shapes and precise bending.
DC04 carbon steel coils have a relatively low carbon content and are commonly used in industries such as automotive, electrical appliances, construction and manufacturing. The high strength and good weldability of DC04 carbon steel coil make it very suitable for the manufacture of parts that need to withstand heavy loads and stresses.
In addition, DC04 steel coils are commonly used in the production of stampings, as well as in the manufacture of furniture, pipes and packaging materials. The versatility and durability of DC04 steel coils make them a popular choice for various application industries.
