ASTM A622 Hot Rolled Carbon Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: ASTM A622 Hot-Rolled Carbon Steel, Drawing Quality** **ASTM A622** is a standard specification for **hot-rolled carbon steel** sheets and strips of **Drawing Quality**. This specification covers steel intended for applications requiring better formability than Commercial Quality steel can provide. The "Drawing Quality" designation indicates the steel is processed to have enhanced ductility and uniformity, making it suitable for parts that will undergo moderate drawing and forming operations. This steel is supplied in the as-hot-rolled condition, characterized by its mill scale surface. --- #### **1. Key International Standards** * **Primary Standard:** **ASTM A622 / A622M** - Standard Specification for Steel, Sheet and Strip, Carbon, Hot-Rolled, Drawing Quality. * **Related/Alternative Standards:** * **ASTM A1011/A1011M:** Standard Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, Drawing Steel (DS) and Structural Steel (SS) - This is the modern comprehensive standard that covers similar materials. * **ASTM A621:** Standard for hot-rolled steel for chain applications. * **SAE J403:** Chemical Compositions for Carbon Steels. * **EN 10111:** Continuously hot-rolled low carbon steel sheet and strip for cold forming. * **JIS G 3131:** Hot-rolled mild steel plates, sheets and strip. --- #### **2. Chemical Composition (Heat Analysis)** The chemical composition for Drawing Quality steel is carefully controlled to maximize formability, typically featuring lower carbon and manganese content than structural grades. | Element | Composition (%) - Typical | Notes | | :--- | :--- | :--- | | **Carbon (C)** | 0.08 max | Very low carbon is essential for good ductility and formability. | | **Manganese (Mn)** | 0.50 max | Lower manganese content enhances formability. | | **Phosphorus (P)** | 0.03 max | Kept low to prevent embrittlement during forming. | | **Sulfur (S)** | 0.035 max | Kept low to improve formability and surface quality. | | **Silicon (Si)** | (Varies by grade) | Typically kept low in drawing quality steels. | *Note: The exact chemical requirements may vary by producer and specific customer requirements for Drawing Quality applications.* --- #### **3. Mechanical & Physical Properties** ASTM A622 steel is characterized by relatively low strength and high elongation compared to commercial quality hot-rolled steels. **Mechanical Properties (Typical):** | Property | Typical Value | Unit | | :--- | :--- | :--- | | **Yield Strength** | 25 - 35 | ksi (172 - 241 MPa) | | **Tensile Strength** | 45 - 55 | ksi (310 - 380 MPa) | | **Elongation (in 2 in / 50 mm)** | 22 - 30 | % | | **Modulus of Elasticity** | ~29,000 | ksi (~200 GPa) | **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:** ~50 W/m·K --- #### **4. Product Applications** The enhanced formability of ASTM A622 Drawing Quality hot-rolled steel makes it suitable for applications requiring more forming than standard hot-rolled steel can accommodate: * **Automotive Components:** Seat frames, brackets, and structural reinforcements that require moderate forming. * **Furniture Components:** Frame parts and structural elements requiring bending and forming. * **General Manufacturing:** Parts that require better formability than commercial quality hot-rolled steel. * **Agricultural Equipment:** Formed panels and components where surface finish is not critical. * **Storage Tanks and Containers:** Formed sections and panels. --- #### **5. Key Advantages** * **Good Formability:** Better ductility and forming characteristics than Commercial Quality hot-rolled steel. * **Cost-Effective:** More economical than cold-rolled steels while offering better formability than standard hot-rolled grades. * **Good Weldability:** The low carbon content enables reliable welding using common methods. * **Good Strength-to-Cost Ratio:** Provides adequate strength for many applications at a lower cost than cold-rolled alternatives. **Disclaimer:** This information is for general reference purposes. For design and critical applications, always consult the latest official **ASTM A622/A622M** standard and technical data sheets from the steel producer. Note that this specification has been largely superseded by ASTM A1011/A1011M for Drawing Quality (DQ) hot-rolled steel. -:- For detailed product information, please contact sales. -: ASTM A622 Hot Rolled Carbon Steel Specification Dimensions Size： Diameter 20-1000 mm Length <4498 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. -: ASTM A622 Hot Rolled Carbon Steel Properties -:- For detailed product information, please contact sales. -:
