Characterized by its exceptional combination of **high strength, excellent fatigue resistance, and superior dimensional consistency**, 0C404 is engineered for demanding flat spring applications where reliability, precision, and durability are critical. It is supplied in a pre-hardened and tempered condition, ready for fabrication without additional heat treatment by the customer. ### **Key Advantages** * **Consistent High Quality:** Exceptional uniformity in hardness, flatness, and temper across the entire coil length and width. * **Optimal Spring Properties:** Delivers an outstanding balance of tensile strength, yield strength, and elastic limit for superior spring performance. * **Excellent Fatigue Life:** High cleanliness steel and controlled processing result in very good resistance to cyclic loading. * **Good Formability:** In its supplied condition, it allows for bending, coining, and blanking to create complex flat spring shapes. * **Ready-to-Use:** Supplied in final hardened and tempered state, eliminating the need for customer heat treatment and associated distortion risks. ### **Chemical Composition (Typical, wt%)** 0C404 is based on a medium-carbon, low-alloy chromium-vanadium steel composition. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 0.50 - 0.60 | **Chromium (Cr)** | 0.60 - 0.90 | | **Silicon (Si)** | 0.15 - 0.35 | **Vanadium (V)** | 0.15 - 0.25 | | **Manganese (Mn)** | 0.60 - 0.90 | **Sulfur (S)** | ≤ 0.030 | | **Phosphorus (P)** | ≤ 0.030 | **Iron (Fe)** | Balance | ### **Physical & Mechanical Properties (Typical, as supplied)** * **Density:** 7.85 g/cm³ * **Modulus of Elasticity (E):** 205 GPa * **Tensile Strength (Rm):** 1700 - 2000 MPa * **Yield Strength (Rp0.2):** 1550 - 1850 MPa * **Hardness:** 480 - 540 HV / 49 - 52 HRC * **Elongation (A₅₀):** 3 - 6% * **Fatigue Strength:** Very high, suitable for dynamic applications. **Note:** Mechanical properties are stable up to an operating temperature of approximately **200°C (390°F)**. Exposure to higher temperatures for prolonged periods will lead to tempering and loss of strength. ### **International Standards & Approvals** Sandvik 0C404 is a proprietary grade that corresponds to or exceeds the requirements of several international standards for hardened and tempered spring steel. * **Sandvik Proprietary Grade:** **0C404** * **Similar/Equivalent Standards:** * **DIN / EN:** 1.2234 (51CrV4) * **ASTM:** A682 (Type: Chromium-Vanadium) * **UNS:** G61500 * **ISO:** 683-14: Spring steels * **Industry-Specific Approvals:** Widely used and accepted in automotive, electrical, and precision engineering industries. ### **Product Applications** Sandvik 0C404 is ideally suited for a wide range of critical flat spring components requiring high strength and fatigue resistance: * **Automotive:** * Seat belt retractor springs * Clutch diaphragm springs * Valve spring discs (retainers) * Brake pad wear indicator springs * Various sensor and actuator springs * **Electrical & Electronics:** * High-current electrical contact springs (e.g., in circuit breakers, switches) * Connector springs * Relay components * **Industrial & Consumer Goods:** * Precision lock springs * High-performance saw blades (bandsaw, hacksaw) * Snap-action disc springs (Belleville washers) * Agricultural machinery springs * Tooling components (e.g., springs in jigs and fixtures) * **General Engineering:** * Flat springs for constant load applications * Complex-stamped spring components ### **Processing Guidelines** * **Forming:** Can be stamped, blanked, and bent in the supplied condition. Tooling must be designed for high-strength materials. Stress-relief annealing (at ~300°C) after severe forming may be recommended for critical applications. * **Machining:** Possible with carbide tools; grinding is the preferred method for precise finishing. * **Surface Treatment:** Readily accepts standard coatings such as phosphating, zinc plating, or painting. For corrosion protection, cadmium or zinc-nickel plating is common. * **Joining:** Can be spot welded or projection welded with appropriate parameters. ### **Availability** Sandvik 0C404 is available as cold-rolled strip with precise dimensional tolerances. * **Thickness:** Typically 0.10 mm to 3.0 mm (custom ranges possible) * **Width:** Up to 330 mm (standard mill capability) * **Condition:** Hardened and Tempered (H&T), bright finish or with protective coating. * **Packaging:** Coils or straight lengths, tailored to customer needs. --- **Important Technical Note:** For design and process validation, it is essential to consult the latest Sandvik technical datasheets and work with their application engineers. They can provide specific property data for your thickness, recommend optimal fabrication processes (like bending radii), and confirm suitability for your application's exact loading and environmental conditions. -:- For detailed product information, please contact sales. -: Sandvik 0C404 Strip Steel Specification Dimensions Size： Diameter 20-1000 mm Length <7440 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Sandvik 0C404 Strip Steel Properties -:- For detailed product information, please contact sales. -:
