Sandvik 20C Pad Printing Strip Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: Sandvik 20C Pad Printing Strip Steel** **1. Product Overview** Sandvik 20C is a high-quality, cold-rolled strip steel specifically engineered for the demanding requirements of pad printing applications. It is characterized by its excellent surface finish, consistent hardness, and superior dimensional accuracy. This material is designed to serve as the durable and reliable plate base for etched pad printing clichés, ensuring precise ink transfer, long production runs, and high-definition print quality. **2. Key Features & Benefits** * **Exceptional Surface Quality:** Provides an ultra-smooth and uniform surface essential for fine and consistent etching of printing patterns. * **Optimized Hardness:** Offers an ideal balance between hardness for wear resistance and ductility for ease of handling and processing. * **High Dimensional Stability:** Guarantees precise flatness and thickness tolerance, crucial for maintaining consistent print pressure and registration. * **Superior Etching Response:** Delivers clean, sharp, and well-defined etch pits for accurate ink well formation. * **Corrosion Resistance:** Good inherent resistance to oxidation and corrosion, prolonging cliché life. * **Consistency:** Sandvik's stringent manufacturing controls ensure batch-to-batch uniformity in performance. **3. Chemical Composition (Typical Analysis)** Sandvik 20C is a high-carbon chromium steel. The typical chemical composition is as follows: | Element | Carbon (C) | Chromium (Cr) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | **Content (%)** | 0.95 - 1.10 | 0.40 - 0.60 | ≤ 0.35 | ≤ 0.40 | ≤ 0.025 | ≤ 0.020 | *Note: The composition may include other minor elements for enhanced properties. This is a representative analysis; specific heats may vary within defined limits.* **4. Physical & Mechanical Properties** * **Hardness:** Typically supplied in a spheroidized annealed condition with a hardness range of **190 - 230 HBW** (Brinell) or approximately **90 - 95 HRB** (Rockwell B). This can be further heat-treated (hardened and tempered) by the customer to achieve higher wear resistance (typically up to 58-62 HRC). * **Tensile Strength:** ~ 600 - 750 MPa (in supplied condition). * **Yield Strength:** ~ 450 MPa (min, in supplied condition). * **Elongation:** ~ 10% (typical). * **Surface Finish:** Bright, smooth finish with minimal surface defects (e.g., Ra < 0.2 µm). * **Flatness:** High degree of flatness as per agreed tolerances. **5. Standard Specifications & Dimensional Tolerances** Sandvik 20C is manufactured to meet or exceed relevant international standards for cold-rolled strip steel. * **Common International Standards:** * **ASTM A681:** Standard Specification for Tool Steels Alloy. * **DIN EN ISO 4957:** Tool steels (similar to grade **100Cr6 / 1.3505**). * **JIS G4404:** Carbon tool steels (similar to **SK3**). * **Common Available Forms:** Coils or straight lengths (sheets/strips). * **Typical Thickness Range:** 0.3 mm to 2.0 mm (custom thicknesses available). * **Typical Width Range:** Up to 650 mm. * **Tolerances:** Supplied to precise tolerances for thickness, width, and flatness as defined in standards such as **DIN EN 10051** or customer-specific requirements. **6. Primary Applications** Sandvik 20C is the preferred material for manufacturing: * **Pad Printing Clichés (Plates):** Used in pad printing for decorating irregularly shaped objects (e.g., consumer electronics, medical devices, automotive parts, toys, promotional items, cosmetics packaging). * **Precision Etched Components:** Suitable for other finely etched industrial parts requiring a good surface finish and wear characteristics. * **Blanking and Forming Tools:** For less complex tooling applications where its hardness and surface quality are beneficial. **7. Processing Guidelines** * **Etching:** Excellent performance in chemical etching processes to create ink wells. * **Machining:** Can be machined (milled, ground) in its supplied annealed state. Post-machining hardening is possible. * **Heat Treatment:** Can be through-hardened by austenitizing, quenching, and tempering to achieve higher surface hardness (e.g., 58-62 HRC) for extreme wear resistance. * **Handling:** Standard steel handling and storage practices apply. Protect from moisture to prevent surface staining. **8. Disclaimer** This information is provided for technical reference only. Properties are typical and may vary.
