ASTM A619 Cold Rolled Carbon Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A619 Cold-Rolled Carbon Steel** **ASTM A619** is a standard specification for **cold-rolled carbon steel** sheets and strips, intended primarily for **welded, riveted, or bolted chain**. This specification covers steel that is cold-rolled to precise dimensional tolerances and mechanical properties, making it suitable for high-stress applications where consistency and reliability are paramount. The steel is produced in two main types: * **Type 1:** Commercial Quality * **Type 2:** Drawing Quality It is supplied in the as-rolled, annealed, or normalized condition, depending on the required properties for the final application. --- #### **1. Key International Standards** * **Primary Standard:** **ASTM A619 / A619M** - Standard Specification for Carbon and Alloy Steel Cold-Finished Bars * *Note: It is important to clarify that ASTM A619 specifically covers cold-rolled strips for chain manufacture. For general-purpose cold-rolled steel sheets, strips, and bars, other standards are more commonly referenced.* * **Related/Alternative Standards:** * **ASTM A108:** Standard for Steel Bars, Carbon, Cold-Finished (a more common standard for general cold-finished bars). * **ASTM A109:** Standard for Steel, Strip, Carbon, Cold-Rolled (a broader standard for general cold-rolled strip). * **SAE J403:** Chemical Compositions for Carbon Steels. * **EN 10277:** Bright steel products - Technical delivery conditions. --- #### **2. Chemical Composition (Heat Analysis)** The chemical composition is tailored to achieve good formability and the necessary strength for chain manufacturing. The following table represents typical ranges for grades commonly associated with this specification, such as **Grade 1006/1008** or **Grade 1010/1015**. | Element | Composition (%) - Typical Grades | Notes | | :--- | :--- | :--- | | **Carbon (C)** | 0.06 - 0.15 max | Low carbon content ensures excellent formability and weldability. | | **Manganese (Mn)** | 0.25 - 0.60 max | Contributes to strength and hardenability. | | **Phosphorus (P)** | 0.04 max | Impurity, kept low to prevent embrittlement. | | **Sulfur (S)** | 0.05 max | Impurity, kept low to improve formability and surface quality. | | **Silicon (Si)** | (Varies by grade) | Deoxidizing agent; content is typically low. | | **Copper (Cu)** | (Varies by grade) | - | *Note: The exact chemical requirements depend on the specific grade ordered (e.g., 1008, 1010, 1015). The low carbon content is a key characteristic.* --- #### **3. Mechanical & Physical Properties** Properties can vary significantly based on the grade, thickness, and temper (cold work condition). The following are **typical ranges** for annealed and hard tempers. **Mechanical Properties (by Temper):** | Condition | Tensile Strength (min) | Yield Strength (min) | Elongation (min) | Hardness (Rockwell) | | :--- | :--- | :--- | :--- | :--- | | **Annealed (Soft)** | 50 - 65 ksi (345 - 450 MPa) | 30 - 45 ksi (205 - 310 MPa) | 20 - 35% | B65 - B80 | | **Hard / Full Hard** | 70 - 90 ksi (485 - 620 MPa) | 65 - 85 ksi (450 - 585 MPa) | 3 - 10% | B84 - B100+ | **Physical Properties (Typical):** * **Density:** 0.284 lb/in³ (7850 kg/m³) * **Modulus of Elasticity:** 29,000 ksi (200 GPa) * **Poisson's Ratio:** 0.29 * **Thermal Expansion Coefficient:** 6.5 x 10^-6 /°F (11.7 x 10^-6 /°C) * **Thermal Conductivity:** ~54 W/m·K (for pure iron; varies with carbon content) --- #### **4. Product Applications** Due to its combination of strength, consistency, and formability, ASTM A619 cold-rolled steel is primarily used in: * **Welded and Weldless Chain:** The primary application, for everything from light-duty proof coil chain to high-test chain for lifting and towing. * **Chain Components:** Links, hooks, and other attachments. * **Staples and Fasteners:** Where precise cold heading and forming are required. * **General Metal Stampings:** For applications requiring a smooth surface finish and consistent properties. * **Springs and Clips:** Especially when made from the harder tempers. --- #### **5. Key Advantages** * **Excellent Surface Finish:** The cold-rolling process produces a smooth, scale-free surface ideal for painting, plating, or other finishing. * **Close Dimensional Tolerances:** Cold-rolling allows for very precise control over thickness, width, and flatness. * **Good Strength and Formability:** Offers a versatile balance that can be tailored through temper and heat treatment. * **Consistent Quality:** The manufacturing process ensures uniform mechanical properties throughout the coil or sheet. * **Good Weldability:** The low carbon content makes it readily weldable by all standard methods. **Disclaimer:** This information is for general reference purposes. The properties and chemical ranges can vary based on the specific grade and condition ordered.
