SPCC 冷轧卷板什么材质｜规格、性能、用途、采购指南

<h1 style="text-align: left;">SPCC Cold-Rolled Coil: Material Guide | Specifications, Performance, Applications & Buying Tips </h1>SPCC SPCC is a general commercial-grade cold-rolled carbon steel coil under the Japanese Industrial Standard JIS G3141. It is one of the most widely used standard cold-rolled materials in domestic manufacturing. Many appliance, hardware, and cabinet manufacturers choose SPCC for stamping, bending, and welding processes.<h3 style="text-align: left;"><h2>1. Understanding the SPCC Grade</h2>Letter Breakdown:‑ S = Steel (钢材)‑ P = Plate (板材)‑ C = Cold (冷轧工艺)‑ C = Commercial (商用普通级)<blockquote>Grade Equivalents: SPCC roughly corresponds to China's Q195/Q215A and Germany's St12. Note the difference between stamping-grade SPCD and deep-drawing grade SPCE. SPCC is suitable for simple bending and standard stamping but not for complex deep-drawing operations.</blockquote><h3 style="text-align: left;"><h2>2. Core Performance of SPCC Cold-Rolled Coils</h2><li style="color: rgb(0, 0, 0);">)">Superior Surface Quality: Cold rolling removes scale, resulting in a smooth, flat surface free of pits or peeling. It offers excellent adhesion for painting and electroplating, making it ideal for visible parts.</li><li style="color: rgb(0, 0, 0);">)">Precision Dimensions: Strict thickness tolerances and flat shape ensure compatibility with automated stamping lines, reducing waste rates.</li><li style="color: rgb(0, 0, 0);">)">Excellent Machinability: Low-carbon content provides good performance for bending, standard stamping, and welding, perfect for hardware casings and frame components.</li><li style="color: rgb(0, 0, 0);">)">Note: SPCC does not rust-proof itself. Storage and finished products require oil coating, painting, or galvanizing for corrosion protection. It is prone to rusting in humid environments.</li></ol><h3 style="text-align: left;"><h2>3. Common Specifications</h2><li style="color: rgb(0, 0, 0);">)">Standard: JIS G3141</li><li style="color: rgb(0, 0, 0);">)">Thickness: Available in 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm</li><li</li><li style="color: rgb(0, 0, 0);">)">Width: Common sizes include 1000mm, 1250mm, 1500mm; custom slit widths available.</li><li style="color: rgb(0, 0, 0);">)">Supply Form: Steel coils, cut-to-length sheets, and slit strips.</li><li style="color: rgb(0, 0, 0);">)">Mill Source: Original material from major mills like Baosteel, Angang, Shougang, Magang, etc., with mill test certificates available.</li></ul><blockquote>Stock Availability: Most common thicknesses range from 0.8‑2.0mm, with 1250mm width being the industry standard raw material size.</blockquote><h3 style="text-align: left;"><h2>4. Primary Applications</h2><li style="color: rgb(0, 0, 0);">)">Appliances: Refrigerators, washing machines, air conditioners (casings, internal brackets, panels).</li><li style="color: rgb(0, 0, 0);">)">Electrical Cabinets: Distribution boxes, control panels, equipment enclosures.</li><li style="color: rgb(0, 0, 0);">)">Hardware & Furniture: Filing cabinets, shelving, metal furniture, lighting fixtures.</li><li style="color: rgb(0, 0, 0);">)">Automotive Parts: Interior trim, general stamping structural parts (select SPCD/SPCE for complex deep-drawing).</li><li style="color: rgb(0, 0, 0);">)">General Manufacturing: Ducts, nameplates, standard stamped parts; also used as substrate for galvanized or color-coated steel.</li></ul><blockquote>Procurement Reminder: If your part cracks during stretching, stop using SPCC and upgrade to SPCD or SPCE. SPCC is cost-effective for bending and shallow-stamping applications.</li></ol><h3 style="text-align: left;"><h2>5. Choosing Between SPCC, SPCD, and SPCE</h2><li style="color: rgb(0, 0, 0);">SPCC)">SPCC: General commercial grade. Best for bending and simple stamping. High cost-performance ratio.Not suitable for deep drawing.</li><li style="color: rgb(0, 0, 0);">SPCD)">SPCD: Stamping grade. Better ductility, suitable for medium-depth forming.</li><li style="color: rgb(0, 0, 0);">SPCE)">SPCE: Deep-drawing grade. High elongation, designed for complex automotive stretch parts.</li></ul><blockquote>Buying Tip: For bending and shallow-casing products, SPCC offers the best value. Avoid using it for deep-drawing tasks to prevent cracking.</blockquote><h3 style="text-align: left;"><h2>6.

Store in dry conditions and apply paint or galvanizing post-production for corrosion protection.Q: Can SPCC replace DC01?A: Yes, for simple bending and stamping applications. However, for export orders, verify execution standards and customer drawings first.Q: What is the maximum thickness available for SPCC?A: Standard market SPCC coils are typically ≤3.0mm. For thicker requirements, hot-rolled pickled steel is recommended.
