AISI 1006 Steel, hot rolled bar, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: ## **Product Specification: AISI 1006 Low Carbon Steel, Hot-Rolled Bar** ### **Product Designation** * **Standard Name:** AISI 1006 / SAE 1006 * **UNS Number:** G10060 * **Condition:** **Hot-Rolled (As-Rolled)** * **Product Form:** **Round Bar** * **Size Range:** **19 mm to 32 mm (0.75 inch to 1.25 inch) diameter** * **Surface:** Characteristic blue/black mill scale. ### **Overview** AISI 1006 hot-rolled round bar is a versatile and economical **very low-carbon steel** supplied in its most basic processed form. The hot-rolling process involves shaping the steel at high temperatures, resulting in a product with good overall integrity, slightly improved mechanical properties over cast material, and a characteristic oxide scale on the surface. Within the specified 19-32 mm (0.75-1.25 in) diameter range, this product offers a practical balance of strength and ductility, making it a fundamental stock material for general fabrication, forging, and machining where high precision or a finished surface is not required in the as-supplied state. --- ### **1. Chemical Composition (Typical % by Weight, AISI/SAE Standard)** AISI 1006 is defined by its minimal alloying, making it a classic "mild steel." | Element | Content (%) | Role & Effect | | :--- | :--- | :--- | | **Carbon (C)** | 0.08 max | **Key characteristic.** Kept very low to ensure excellent weldability, formability, and ductility. Provides minimal strength contribution. | | **Manganese (Mn)** | 0.25 - 0.40 | Aids in deoxidation during steelmaking and provides slight solid solution strengthening. | | **Phosphorus (P)** | 0.040 max | Impurity; controlled to maintain cold workability. | | **Sulfur (S)** | 0.050 max | Impurity; can affect surface finish and weldability if too high. | | **Iron (Fe)** | Balance (~99.4%) | Primary constituent. | | **Note:** Silicon content is typically low but depends on the deoxidation practice (e.g., killed, semi-killed). | --- ### **2. Physical & Mechanical Properties (Hot-Rolled Condition, 19-32 mm round)** **A. Physical Properties** * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Elastic Modulus (E):** 200 GPa (29,000 ksi) * **Poisson's Ratio:** 0.29 * **Thermal Conductivity:** ~63 W/m·K (High) * **Coefficient of Thermal Expansion:** 11.7 x 10⁻⁶ /K * **Magnetic Properties:** Strongly ferromagnetic. **B. Mechanical Properties (Typical, As-Hot-Rolled)** *Properties are generally isotropic (uniform in all directions) due to the hot-working process.* * **Yield Strength (0.2% Offset):** 230 - 310 MPa (33 - 45 ksi) * **Tensile Strength:** 330 - 415 MPa (48 - 60 ksi) * **Elongation in 50 mm:** **25% - 35%** (Very good ductility) * **Hardness (Brinell):** 95 - 120 HB * **Surface Finish:** Covered in a tenacious, dark blue/black iron oxide layer (mill scale). Must be removed (e.g., by pickling, shot blasting, or machining) for painting, plating, or precise welding. * **Dimensional Tolerance:** Meets standard hot-rolled bar tolerances (e.g., ASTM A29), which are wider than for cold-drawn products. Diameter and straightness are suitable for general purpose use. * **Machinability:** **Fair.** The soft, ferritic structure can be gummy, leading to built-up edge on tools and stringy chips. Machinability improves with higher sulfur "free-machining" variants (e.g., 1008). * **Hardenability:** **Effectively none.** Cannot be strengthened by heat treatment. --- ### **3. Product Applications** Hot-rolled AISI 1006 round bar in this size range is a workhorse material for general industrial and construction use. * **General Fabrication & Welding:** * Structural frames, supports, brackets, and handrails where the scale can be removed and the part painted. * Base material for welded assemblies in agricultural equipment, storage racks, and furniture. * **Forging Stock:** * An excellent and economical starting material for hot-forged parts like simple levers, hooks, brackets, and agricultural tines. * **Machined Parts (with scale removal):** * Bushings, spacers, weights, and non-precision shafts where the final dimensions are achieved by machining away the scaled surface. * **Construction & Reinforcing:** * Tie rods, anchor bolts, and dowels in non-critical concrete or masonry applications. * **General Purpose Hardware:** * Raw material for the manufacture of simple fasteners, pins, and rods after further processing (drawing, heading). --- ### **4. International Standards & Designations** | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **SAE / AISI (USA)** | **SAE 1006 / AISI 1006** | The standard grade designation. | | **UNS (USA)** | **G10060** | Unified Numbering System. | | **ASTM (USA)** | **ASTM A36** (Structural) often applies for bar in this range. **ASTM A575** (Merchant Quality) or **A576** (Special Quality) are also common specifications for hot-rolled carbon steel bars. | A36 covers a wider chemistry but similar properties; 1006 is often supplied to these general ASTM specs. | | **DIN / EN (Germany/EU)** | **S235JR (1.0038)** | The most common European structural steel equivalent for hot-rolled products, with a 235 MPa minimum yield strength. **DD11 (1.0338)** is also similar. | | **JIS (Japan)** | **SS330, SS400** | General structural steel grades. SS330 is closer in strength. | | **GB (China)** | **Q235B, Q195** | Common Chinese grades for hot-rolled carbon steel. Q235 is a direct functional equivalent. | | **ISO** | **ISO 630-2: E235B** | International standard for structural steel. | --- ### **Key Processing Notes** 1. **Scale Removal:** Essential for most applications. Methods include pickling (acid bath), shot/sand blasting, or milling/turning. 2. **Weldability:** **Excellent.** Can be welded by all common processes (SMAW, GMAW, GTAW, etc.) without pre-heat or post-heat treatment. The heat-affected zone (HAZ) will not harden. Scale must be removed at the joint for quality welds. 3. **Cold Bending/Forming:** Good formability, though the mill scale may flake off during bending. 4. **Straightening:** Bars may require cold straightening if critical straightness is needed. ### **Summary** **AISI 1006 hot-rolled round bar in the 19-32 mm (0.75-1.25 in) size range is a fundamental, cost-effective commodity steel product.** It provides a readily available, weldable, and formable raw material for a vast array of general manufacturing, fabrication, and forging applications. Its value lies in its simplicity, economy, and ease of use in processes that will further define its final shape and finish. While it lacks the precision, strength, and surface quality of cold-finished steels, it serves as the essential starting point for countless industrial components and structures worldwide, with direct functional equivalents such as **ASTM A36, EN S235JR, and GB Q235B**. -:- For detailed product information, please contact sales. -: AISI 1006 Steel, hot rolled bar, 19-32 mm (0.75-1.25 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <4735 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. -: AISI 1006 Steel, hot rolled bar, 19-32 mm (0.75-1.25 in) round Properties -:- For detailed product information, please contact sales. -:
