Hemaokang Steel (Shandong) Co., Ltd. is proud to offer our Cold Rolled Carbon Steel Coil with thickness from 0.5mm to 2.0mm and a tight tolerance of ±0.05mm, specifically engineered for precision stamping applications. As a newly established but rapidly growing exporter with an annual export value of US$50-100 million, we combine modern production capabilities with rigorous quality control to deliver coils that meet the exacting demands of industries such as automotive, electronics, and appliance manufacturing. Our commitment to consistency and dimensional accuracy ensures that every coil performs reliably in high-speed stamping presses, reducing scrap and enhancing productivity.
This product is manufactured using advanced cold rolling technology, which provides a smooth surface finish, excellent flatness, and uniform mechanical properties. The ±0.05mm tolerance guarantee minimizes material waste and ensures that finished parts meet tight specifications. Whether you require coils for progressive die stamping, transfer stamping, or fine blanking, our CRC coil offers the ideal balance of strength, ductility, and surface quality. Below are the key technical specifications and benefits.
Key Features & Technical Specifications
- Precision Thickness Control: ±0.05mm tolerance across the entire coil ensures consistent part dimensions.
- Wide Thickness Range: 0.5mm to 2.0mm, suitable for a variety of stamping depths and complexities.
- High Surface Quality: Bright or matte finish reduces tool wear and improves formability.
- Excellent Mechanical Properties: Customizable hardness levels (full hard, half hard, etc.) to match your stamping process.
- Uniform Flatness: Minimizes camber and crossbow for trouble-free feeding in automatic presses.
- Customizable Width: Available in widths from 600mm to 1500mm, slit to your exact requirements.
- ISO9001 Quality Management: Our production follows ISO9001 standards, ensuring repeatable quality.
Typical Mechanical Properties (Reference)
| Property | Value Range |
| Tensile Strength | 270 – 550 MPa (depending on grade) |
| Yield Strength | 140 – 350 MPa |
| Elongation | 20% – 40% |
| Hardness (HRB) | 50 – 85 (customizable) |
Benefits for Precision Stamping
- Reduced Tool Wear: Consistent material properties and smooth surface extend die life.
- Higher Yield: Tight tolerance means fewer rejects and more conforming parts per coil.
- Process Stability: Uniform flatness and thickness allow for stable stamping speeds.
- Versatility: Suitable for both simple and complex stamping geometries.
Our coils are available in standard grades such as SPCC, SPCD, SPCE (JIS), or equivalent DC01/DC03/DC04 (EN), and can be supplied with mill edge or slit edge. We also offer various surface treatments like oiling, drying, or passivation upon request. Each coil is carefully packaged with anti-rust paper and steel strapping to ensure it arrives in perfect condition.

Frequently Asked Questions (FAQ)
1. What is the minimum order quantity (MOQ) for this product?
Our standard MOQ is 20 metric tons per size, but we can accommodate smaller trial orders for new customers. Please contact our sales team for details.
2. Can you provide coils with a specific width?
Yes, we offer slitting services to customize widths from 600mm up to 1500mm. Tolerances for width are ±1mm as standard, with tighter tolerances available upon request.
3. What surface treatments are available?
We can supply coils with bright finish, matte finish, oiled, dry, or passivated surfaces. The choice depends on your stamping process and storage conditions. Let us know your preference.
4. How do you ensure the thickness tolerance of ±0.05mm?
We use advanced automatic gauge control (AGC) systems during cold rolling and perform 100% inspection at the exit of the line. Additionally, we randomly sample coils for third-party verification if required.
5. Is the coil suitable for deep drawing or complex stamping?
Yes, we offer a range of grades from commercial quality (SPCC/DC01) to deep drawing quality (SPCD, SPCE/DC03, DC04). The higher ductility grades are ideal for deep drawing applications. Please specify your forming requirements.
6. What certifications do you have?
Our company is ISO9001 certified, and we can provide mill test certificates for each coil. Additional certifications (e.g., ASTM, JIS) can be supported upon request, subject to your specific requirements.
7. How long is the lead time for a typical order?
For standard specifications, lead time is approximately 15-20 days from confirmation of order and payment. Custom sizes or special finishes may require 25-30 days. We always aim to meet your project deadlines.
8. Can you ship to my country?
We export to 20+ countries worldwide, including North America, South America, Europe, Asia, Africa, and Oceania. We have experience with international shipping documentation and can arrange door-to-door delivery if needed.
