Ovako C45E EN 10083-2:2006 Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Ovako C45E Steel per EN 10083-2:2006** **Ovako C45E (EN 10083-2:2006)** is a **medium-carbon, non-alloy quality steel for engineering applications**, produced by Ovako in strict compliance with the European standard EN 10083-2. The suffix **"E"** specifically denotes its designation as an **Engineering steel** within this standard, indicating its intended use for parts subjected to mechanical stresses that will undergo thermal treatment (quenching and tempering). This product represents the standard-bearer for reliable, through-hardenable carbon steel in European engineering. It is characterized by a well-defined chemical composition and specified mechanical properties after heat treatment. Ovako's manufacturing ensures consistent quality that meets or exceeds the standard's requirements, making it a fundamental and trusted material for a vast array of mechanical components. --- ## **1. Chemical Composition (Per EN 10083-2:2006 - Grade 1.0503)** The standard defines precise compositional limits for the C45E grade, which Ovako adheres to with typical production at the mid-range for optimal performance. | Element | Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Copper (Cu) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | **EN 10083-2 Limits for C45E** | 0.42 - 0.50 | ≤ 0.40 | 0.50 - 0.80 | ≤ 0.035 | ≤ 0.035 | ≤ 0.30 | | **Ovako Typical Production** | 0.45 - 0.48 | 0.15 - 0.30 | 0.60 - 0.75 | **≤ 0.025** | **≤ 0.025** | < 0.20 | | **Key Role** | Primary source of strength & hardenability. | Deoxidizer. | Main alloying element for hardenability. | Impurity; controlled for toughness. | Impurity; controlled for uniformity. | Residual element. | **Critical Features of the C45E Designation:** * **Standardized Engineering Grade:** The "E" suffix formally classifies it within EN 10083-2 for engineering applications requiring heat treatment, distinguishing it from other steel categories. * **Optimized for Through-Hardening:** The combined carbon (0.42-0.50%) and manganese (0.50-0.80%) content provides the necessary hardenability for effective quenching and tempering, especially in oil. * **Enhanced Quality (Ovako's Practice):** While the standard permits up to 0.035%, Ovako typically controls phosphorus and sulfur to **≤0.025%**. This results in **superior impact toughness and more isotropic properties** compared to the minimum standard, reducing the risk of brittle fracture. * **Material Designation:** Fully identified as **EN 10083-2 | 1.0503 | C45E**. --- ## **2. Physical & Mechanical Properties** EN 10083-2 specifies minimum mechanical properties for C45E **in the quenched and tempered condition**. The properties are a function of the tempering temperature, which is agreed upon between supplier and customer. The standard also allows for supply in other conditions (e.g., +N). **A. Properties after Quenching & Tempering (Reference from Standard):** *Typical for a tempering temperature around 550-600°C.* | Property | **Typical Range / Minimum** | **Condition & Note** | | :--- | :--- | :--- | | **Tensile Strength (Rm)** | 700 - 850 MPa | Varies with tempering temperature. | | **Yield Strength (Rp0.2)** | **≥ 450 MPa** | | | **Elongation (A₅)** | **≥ 14%** | | | **Impact Energy (KV)** | **≥ 35 J (Longitudinal, at 20°C)** | A key measure of toughness. | | **Hardness** | ~ 210 - 250 HB | Corresponds to the tensile strength range. | **B. Common Delivery Conditions from Ovako:** 1. **+QT (Quenched & Tempered):** Supplied to a specific, agreed tensile strength (e.g., 900 MPa, 1000 MPa), with a full 3.1 inspection certificate. 2. **+N (Normalized):** Provides a fine-grained, uniform ferrite-pearlite structure ideal for machining prior to customer hardening. Properties: Rm ~ 650-750 MPa, HB ~ 180-220. 3. **+AR (As-Rolled):** The most economical form for further hot working or processing. --- ## **3. Product Applications** C45E is one of the most widely used engineering steels in Europe, serving as the backbone for countless mechanical components. * **General Mechanical Engineering:** **Shafts, spindles, axles, gears, bolts (Property Class 8.8), couplings, and lever arms.** * **Automotive Industry:** **Steering components (stub axles, pins), crankshafts, connecting rods, and various stressed parts.** * **Hydraulic & Pneumatic Systems:** **Piston rods, cylinder barrels** (often surface-hardened). * **Tooling & Machine Construction:** **Jigs, fixtures, dies, and machine tool components** requiring wear resistance. * **Agricultural & Construction Machinery:** **Drive shafts, linkage parts, pins, and gears.** --- ## **4. International & Equivalent Standards** EN 10083-2 C45E is part of a globally harmonized system for engineering steels. | Standard System | Equivalent Grade | **Status / Relationship** | | :--- | :--- | :--- | | **EN (Governing Standard)** | **EN 10083-2:2006 - 1.0503 (C45E)** | **The defining specification** for this product. | | **DIN** | **1.0503 (Historically Ck 45)** | German origin, now fully integrated into EN. | | **ISO** | **ISO 683-18: Type 1.0503** | International equivalent. | | **AISI/SAE (USA)** | **1045** | Direct chemical equivalent. **Note:** The "E" designation has no direct AISI equivalent; it indicates compliance with the EN standard's engineering steel rules. | | **JIS (Japan)** | **S45C** | Very close equivalent. | | **GB (China)** | **45# Steel** | Chinese equivalent. | | **Ovako Proprietary** | e.g., **C45 5155** | Ovako's internal specs often use C45E as a baseline but may include tighter controls or special processing. | **Key Distinction:** Specifying **"Ovako C45E EN 10083-2:2006"** is a precise demand for a material that **conforms to all mandatory requirements of that published European standard**. This is essential for regulatory compliance, quality audits, and design within the EU framework. It is different from ordering a generic "C45" or a manufacturer's proprietary grade. --- ## **5. Key Advantages & Considerations** **Advantages:** * **Guaranteed Standard Compliance:** Provides assurance of material quality, traceability, and fitness for purpose according to a major international norm. * **Proven Reliability:** Decades of industrial use have established its performance characteristics and processing guidelines. * **Excellent Cost-Performance Ratio:** As a non-alloy steel, it delivers high strength after heat treatment at a relatively low material cost. * **Versatile Heat Treatment Response:** Well-suited for quenching & tempering, induction hardening, flame hardening, and normalizing. * **Good Machinability in Soft State:** In the normalized or annealed condition, it allows for efficient machining prior to hardening. **Considerations:** * **Moderate Hardenability:** Its hardenability is limited by its plain carbon-manganese composition. Fully through-hardening is effective typically for sections **up to approx. 30-40mm** in diameter (oil quench). Larger sections may have a softer core. * **Requires Final Heat Treatment:** To achieve high strength, quenching and tempering are mandatory. * **Standard Inclusion Levels:** The EN 10083-2 standard does not specify special cleanliness. For highly fatigue-critical applications, a steel with defined inclusion control (e.g., Ovako's "4M" quality) is recommended. * **Weldability:** Requires precautions (pre-heat, low-hydrogen electrodes, post-heat) due to its carbon content. Not ideal for heavily welded structures. --- **Disclaimer:** When procuring this material, the **delivery condition (e.g., +QT to Rm 900 MPa, +N, +AR) must be explicitly stated in the purchase order**. The standard provides property ranges, but the exact agreed values are contract-specific. For design and qualification, always rely on the **Inspection Certificate 3.1 per EN 10204** provided by Ovako, which certifies the actual properties of the supplied batch against the ordered standard and condition. -:- For detailed product information, please contact sales. -: Ovako C45E EN 10083-2:2006 Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5088 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. -: Ovako C45E EN 10083-2:2006 Steel Properties -:- For detailed product information, please contact sales. -:
