Cold Rolled Carbon Coil (CRC) for Stamping, Home Appliance & Deep Drawing Applications
Cold Rolled Carbon Coil (CRC) starts as hot rolled coil. That coil gets cold-reduced at room temperature. Annealing and temper rolling come after. What comes out is a flat steel product built to tight precision. Tianjin Youcheng Technology Co., Ltd. brings 12 years of experience in steel stocking and distribution, plus export work. Around 200 tons sit in stock for prompt delivery. Grades on hand include SPCC, SPCD, SPCE, Q195, and Q235B. Thickness runs from 0.2 mm to 3.0 mm. Widths come in 1000 mm and 1250 mm. Custom-slit sizes are available too. The steel conforms to GB/T 708 and ASTM A1008.
What Is Cold Rolled Carbon Steel Coil?
Hot rolled coil runs through rolling mills at room temperature to make cold rolled carbon steel coil. Recrystallization temperature sits higher than that. Set against hot rolled steel, this process improves a few things. Surface quality is better. Dimensional accuracy is tighter. Mechanical properties hold up better too.
Thickness tolerances come out tighter after cold reduction. They usually land within ±0.03 mm to 0.05 mm. The surface ends up flat and smooth. It performs well on high-speed automated manufacturing lines.
Annealing after the rolling step gives back the ductility that cold reduction takes away. The material can then be formed into complex shapes without cracking. Stamping lines and home appliance parts both count on this.

Key Product Advantages
Smooth, bright surface finish: Cold rolling leaves behind a clean surface with an even texture. Paint, galvanizing, or powder coating will take to it straight away. No extra prep work is needed first.
Reliable deep drawing and stamping performance: Deep drawing jobs often call for grades like SPCD and SPCE. Their carbon content stays low, so the steel remains ductile. That is what stops it from cracking once forming stress builds up.
Consistent thickness across the coil width: Thickness stays even from one edge of the coil to the other. That tight control over dimensions keeps press lines and roll-forming work steady. It also means less waste and less rework.
Suitable as base material for GI and PPGI: Coatings need something to grip. A clean surface that reacts well lets zinc and pre-painted finishes bond properly. This productis the standard base for galvanized and color-coated coil production.
Available in oiled or unoiled surface: Oiled or unoiled, whichever you need. Oil on the surface stops oxidation while the coil travels and sits in storage. Oil weight can be set to match your storage time and your downstream process.
Quality Control Process
Every coil gets checked at the factory before it ships. Dimensions are verified. The surface is inspected. Hardness gets tested as well. All of this confirms the material matches the specs on your order.
Inspection typically includes:
- Tensile and elongation testing to verify ductility for stamping applications
- Dimensional verification for thickness uniformity across the coil width
- Surface condition inspection to confirm suitability for coating and painting
- Chemical composition analysis to confirm carbon and manganese levels match the specified grade
- Shape and flatness assessment to support downstream cutting and blanking operations
Mill Test Certificates (MTC) are provided for every shipment. ISO and RoHS compliance documentation is available on request.
Application Scenarios
Industries turn to Cold Rolled Carbon Coil (CRC) when surface quality and steady dimensions matter.
Automotive manufacturing: Goes into exterior body panels and parts inside the structure. It forms well and holds its dimensions, so it suits complex pressed parts that need tight tolerances.
Home appliances and electronics: Refrigerator cabinets need CRC. Washing machine drums and computer cases need it too. Flatness is the main reason. The surface has to stay intact as well. Paint and pre-coated layers then sit on a base that holds.
Precision engineering and infrastructure: HVAC ductwork works well with CRC. Same goes for steel furniture and light-gauge structural profiles. The steel runs through roll-forming and blanking without trouble, run after run.
Base material for downstream processing: Plants that produce galvanized steel (GI) and pre-painted galvanized iron (PPGI) start with CRC. It acts as the base layer on those lines.

FAQ
Q: In the main way, how does CRC differ from hot rolled coil?
A: This productgoes through cold reduction. That is what makes its surface smoother and its tolerances tighter. Its yield strength is higher too. Hot rolled coil is the other case. Scale covers its surface, and its dimensions are less exact.
Q: What stops corrosion while the product is being shipped and stored?
A: CRC goes out with a film of protective oil on the surface. Packaging follows export seaworthy standards. When storage will run longer, a heavier oil weight can be ordered instead.
Q: Can CRC be welded in automated production lines?
A: Yes. The carbon content stays low, and the surface is clean. That suits resistance spot welding. MIG and TIG work as well. These processes are used all the time in automotive and appliance manufacturing.
Q: What surface finishes are available?
A: Two standard finishes are on offer. Dull finish holds lubricants well, so it is the one people pick when the part will be painted. Bright finish is the other, and it goes into decorative plating work.
Q: What does annealing do to the material?
A: Cold reduction strips ductility out of the steel. Annealing after rolling brings it back. With that ductility restored, CRC can be formed into deep-drawn shapes, and it will not crack or tear.
Q: Can we get custom slitting and cut-to-length done here?
A: Yes. We do slitting. Blanking is available too. Leveling and cut-to-length are also on the list. Send over the width you need. The length too. And the grade. We will check and get back to you with availability and lead time.
