Products Description

What Is CRc Coil?

Cold rolled steel coil (CRc coil) is essentially hot-rolled steel. After the scale is removed by pickling, it is continuously cooled at room temperature and then annealed and temper-rolled. During continuous cold rolling, the strength and hardness of the hard rolled coil increase, and the ductility and plasticity decrease. Also, the steel coil is with tighter dimensional tolerances and better surface finishes.

Cold rolled to exact specifications:

We produce cold rolled strip and cold rolled plate to your specifications. Cold rolled steel is highly engineered steel made from a hot rolled base material. Cold rolling changes the mechanical properties of steel to better meet the specifications of unlimited applications.

Features Of CRC Cold Rolled Steel Coils Products:

The rolling deformation of metal below the recrystallization temperature is called cold rolling.

Cold rolled steel strip generally refers to the strip steel being rolled directly at room temperature without heating. Although, due to the distortion of the metal during cold rolling, a large amount of deformation heat is generated. Therefore, the strip steel may be hot after rolling, but it is still called cold rolling.

crc

Accurate size, uniform thickness, and small tolerance.
It can roll very thin products.
The surface quality of strip steel is good, and the finish is controllable.
Has good mechanical properties and process properties (such as stamping properties).

Commonly Used Steel Codes:

DC01 (tensile strength 270 – 410 MPa)– This grade can be used for simple forming work such as using bending, embossing, crimping, and stretching.

DC02/DC03 – These grades are suitable for forming requirements such as deep drawing and difficult profiles.

DC04 – This quality can meet high deformation requirements.

DC05/06/07 – These deep drawing quality grades are suitable for higher forming and deformation requirements. Below are their mechanical properties.

Steel Code	Yield Strength	Tensile Strength	Elongation A80mm	Plastic Strain Ratio r90	Strain Hardening Exponent n90
DC01(10130)	140-280 MPa	270-410	≥28
DC02	140-240 MPa	270-370 MPa	≥34	≥1.4
DC03	120-210 MPa	270-350 MPa	≥38	≥1.8	≥0.18
DC04	120-180 MPa	270-350 MPa	≥40	≥2.0	≥0.20

SPCC, SPCD, SPCE Materials

Steel Code	Yield Strength Relb	Tensile Strength	Plastic strain ratio r90e	Strain hardening exponent n90d
SPCC	130-300 MPa	270-410 MPa
SPCD	120-240 MPa	270-370 MPa	≥1.3
SPCE	120-210 MPa	270-350 MPa	≥1.8	≥0.18

Coil is divided into chilled coil plate and cold rolled coil plate:

Chilled Coil are obtained by pickling and cold rolling of hot-rolled coils plate. It is a cold rolled coil plate. Cold-rolled coil plate (annealed): It can be obtained from hot-rolled coils plate through pickling, cold rolling, bell annealing, flattening, (finishing) processing.

There are three main differences between the two:Generally the default delivery state of cold rolled coil plate is annealed state.

1. In appearance, the color of chilled coils plate is generally micro black color.

2. In terms of surface quality, structure, and dimensional accuracy, cold-rolled coil plate are better than chilled coils plate.

3. In terms of performance, because the chilled coils plate directly obtained from the hot-rolled coils plate through the cold rolling process undergo work hardening during cold rolling, the yield strength is increased, and some internal stresses remain, and the external performance is relatively "hard". Called chilled coil plate. And cold-rolled coil plate (annealed): It is obtained from the chilled coil plate through bell annealing before coiling. After annealing, the work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength decreases close to the cold Before rolling. Due to the yield strength, chilled coils are larger than cold-rolled coils plate (annealed), making cold-rolled coils plate (annealed) more conducive to stamping and forming.
