AISI 1015 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: ## **Product Specification: AISI 1015 Low Carbon Steel, Hot-Rolled Bar** ### **Product Designation** * **Standard Name:** AISI 1015 / SAE 1015 * **UNS Number:** G10150 * **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:** Standard hot-rolled finish with adherent, dark mill scale. * **Key Feature:** An economical, versatile, and widely available mild steel with excellent weldability and good machinability, ideal as stock for forging, fabrication, or further processing. ### **Overview** AISI 1015 hot-rolled round bar is a fundamental and cost-effective form of low-carbon steel. Produced by rolling at high temperatures, it offers good internal soundness and consistent mechanical properties within the 19-32 mm cross-section. This grade is distinguished by its balanced carbon content, which provides a solid foundation for strength, good machinability, and excellent suitability for **case hardening (carburizing)**. It serves as a primary raw material for a broad spectrum of industrial applications, from structural components to forged parts, where the final dimensions and surface are achieved through subsequent machining or forming. --- ### **1. Chemical Composition (Typical % by Weight, AISI/SAE Standard)** | Element | Content (%) | Role & Effect | | :--- | :--- | :--- | | **Carbon (C)** | 0.13 - 0.18 | **Primary strengthening element.** This range provides a good balance: it offers improved strength and machinability over 1010, and is the optimal level for effective carburizing to create a hard, wear-resistant surface. | | **Manganese (Mn)** | 0.30 - 0.60 | Enhances strength and contributes to hardenability. Important for achieving a good case depth during heat treatment. | | **Phosphorus (P)** | 0.040 max | Impurity; controlled for formability. | | **Sulfur (S)** | 0.050 max | Impurity; standard level. | | **Iron (Fe)** | Balance | Primary constituent. | --- ### **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:** ~59.5 W/m·K * **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 due to hot working.* * **Yield Strength (0.2% Offset):** 325 - 420 MPa (47 - 61 ksi) * **Tensile Strength:** 460 - 580 MPa (67 - 84 ksi) * **Elongation in 50 mm:** **18% - 26%** (Good ductility) * **Hardness (Brinell):** 125 - 170 HB * **Surface Finish:** Covered in a tenacious mill scale (iron oxide) that must be removed via blasting, pickling, or machining for most finishing operations. * **Dimensional Tolerance:** Meets standard commercial hot-rolled bar tolerances (e.g., ASTM A29), suitable for general fabrication but not for precision applications without machining. * **Machinability:** **Good to Very Good.** The carbon content reduces gumminess, promoting better chip formation than lower-carbon grades like 1008 or 1010. It is a commonly machined hot-rolled grade. * **Case Hardenability:** **Excellent (after carburizing).** A premier attribute. It can be readily carburized to produce a hard surface (up to ~65 HRC) with a tough, ductile core, making it a classic choice for wear parts. --- ### **3. Product Applications** Hot-rolled AISI 1015 bar in this medium size range is a staple for general manufacturing, forging, and fabrication. * **Forging Stock:** A popular and economical choice for hot-forged components such as levers, linkages, hooks, hand tools, and flanges where good machinability post-forging is beneficial. * **Machined Parts (After Descaling):** Components like bushings, spacers, brackets, and flanges where final dimensions are achieved by machining. * **Structural & Fabricated Components:** Frames, supports, base plates, and brackets in agricultural, material handling, and light structural applications. * **Shafts, Pins, and Axles (Non-Critical):** Pivot pins, hinge pins, rollers, and light-duty axles. * **Case Hardening Substrate:** One of the most common steels selected for parts destined for carburizing, such as gears, camshafts, wear plates, and low-stress bearing surfaces. * **General Hardware:** Raw material for standard fasteners, pins, and other hardware items. --- ### **4. International Standards & Designations** | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **SAE / AISI (USA)** | **SAE 1015 / AISI 1015** | The standard grade designation. | | **UNS (USA)** | **G10150** | Unified Numbering System. | | **ASTM (USA)** | **ASTM A36** (Structural), **ASTM A575** (Merchant Quality), **ASTM A576** (Special Quality) | Often supplied under these broader ASTM specifications which cover similar property ranges. | | **DIN / EN (Germany/EU)** | **S235JR (1.0038), C15 (1.0401)** | **S235JR** is a common structural steel equivalent. **C15** is a quality steel for heat treatment with similar chemistry. | | **JIS (Japan)** | **SS400, S15C** | **SS400** for structural use; **S15C** (JIS G4051) is the direct equivalent for steel bars. | | **GB (China)** | **Q235B, 15** | **Q235B** is a dominant structural steel equivalent. **15** (GB/T 699) is the direct chemical equivalent. | | **ISO** | **ISO 630-2: E235B, ISO 683-1: C15E** | E235B for structural steel; C15E for engineering steel. | --- ### **Key Processing Notes** 1. **Scale Removal:** Essential for painting, plating, precision welding, or accurate machining. Achieved via abrasive blasting, pickling, or turning. 2. **Weldability:** **Excellent.** No pre-heat or post-heat treatment required for most welding processes. The low carbon equivalent minimizes risk of hardening in the HAZ. 3. **Cold Bending/Forming:** Good formability; mill scale will crack and spall during bending. 4. **Heat Treatment Advantage:** Its primary value-added process is carburizing. The low carbon core ensures toughness, while the surface becomes extremely hard and wear-resistant. 5. **Economic Efficiency:** Provides the lowest-cost entry point for parts that will be fully machined or forged, where the initial surface condition is not critical. ### **Summary** **AISI 1015 hot-rolled round bar (19-32 mm) is a versatile and economical workhorse material that forms the backbone of countless general engineering and manufacturing applications.** Its balanced chemistry provides a reliable combination of strength, ductility, weldability, and **exceptional suitability for case hardening**. While it lacks the precision and finish of cold-drawn products, its low cost, wide availability, and excellent processing flexibility make it the default choice for forging stock, fabricated components, and as a substrate for carburized parts. Its properties are closely aligned with common international grades like **ASTM A36, EN S235JR, and GB Q235B**, ensuring its global relevance and utility. -:- For detailed product information, please contact sales. -: AISI 1015 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <4753 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 1015 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Properties -:- For detailed product information, please contact sales. -:
