Crc Sheet In Coil Cs Type B
product details
product description
What is Crc Sheet In Coil Cs Type B?
"CS" generally stands for "Commercial Steel," while "B-type" specifically refers to a chemical composition design with a higher phosphorus (P) content compared to Type A (Aluminum Killed). This subtle chemical adjustment imparts unique mechanical properties and deep-drawing characteristics. Cold rolling, after hot-rolled and pickled, further reduces the hot-rolled, pickled coil at room temperature to achieve thinner thicknesses, higher dimensional accuracy, and superior surface quality.
In short, crc sheet in coil Cs Type B is a commercial-grade, cold-rolled carbon structural steel with excellent formability and surface quality at an exceptionally cost-effective price. It offers an excellent balance of performance and cost, making it an ideal choice for a wide range of stamping, bending, and shallow drawing processes.

Manufacturing process
During the manufacturing process, CS Type B cold rolled steel coil Automotive Plate needs to undergo multiple precision rolling and annealing processes to obtain its excellent mechanical properties.
At the same time, in order to ensure the quality and reliability of the materials, various quality inspections and control measures are required during the manufacturing process, such as surface quality inspection, mechanical properties testing, metallographic structure analysis, etc.
CS type b chemical composition
CRC cold rolled steel coil CS Type B is a high-strength low-alloy structural steel widely used in automobiles, machinery and building structures. Its chemical composition mainly includes carbon, manganese, silicon, phosphorus, sulfur and chromium.
Outstanding Features and Advantages
Despite annealing and softening, its inherent strength surpasses that of many competing materials. Through proper composition design and process control, a higher strength-to-weight ratio can be achieved while maintaining good formability, contributing to lightweighting.
CS B cold-rolled steel offers these high performance characteristics while typically being priced lower than deep-drawing (DS/DDQ) or extra-deep-drawing (EDDQ/EDDS) grades. For applications not requiring extreme deep-drawing properties, choosing CS B is a wise choice for cost optimization and product competitiveness.
Formability
After annealing, the internal grain size is uniform and fine, resulting in high elongation and uniform plastic deformation.
Uniform Thickness
The cold rolling process is controlled by a sophisticated computer system, enabling extremely precise control of thickness and width.
Weldability
CS B cold-rolled steel, with its pure composition and clean surface, exhibits excellent weldability and can be joined using various methods, including spot welding and arc welding, resulting in strong welds.
Paintability
Its uniform surface also facilitates surface treatments such as phosphating, galvanizing (post-treatment), and painting, resulting in excellent coating adhesion and uniformity.
Surface Quality
The cold rolling process ensures a smooth, clean, and uniform surface. Common surface finishes include:
Glossy: The surface is smooth and reflective, offering a high aesthetic appeal.
Rough/Matte: Sandblasted or treated with an electrospark treatment, the surface is subtly contoured, facilitating subsequent coating and plating adhesion and concealing minor scratches.
This high-quality surface is suitable for direct use as exterior components or after minimal processing.

How to correctly select and purchase CS B cold-rolled steel?
Choosing the right material is half the battle. We recommend considering the following aspects:
Mechanical Properties: Determine the tensile strength, yield strength, and elongation required for your product. This directly determines whether the material can be successfully formed and meet the required strength requirements.
Thickness and Tolerance: Determine the most economical thickness and tolerance range based on the part design and application requirements. We can provide high-precision products within ±0.03mm.
Surface Condition and Finish: Choose a glossy, matte, or matte finish? Is oiling required? What type of oil should be used and how much should be applied? This affects subsequent processing and surface treatment.
Dimensions: Do you need coils (suitable for continuous stamping) or cut-to-length sheets? What is the required width and coil weight?
Standards and Certifications: Does the product need to comply with specific international/national standards (such as ASTM A1008, JIS G 3141, EN 10130) or industry certifications (such as IATF 16949 for the automotive industry)? We guarantee that all products come with a comprehensive warranty (MTC/Mill Test Certificate).
