AISI 1015 Steel, as rolled Product Information -:- For detailed product information, please contact sales. -: ## **Product Specification: AISI 1015 Low Carbon Steel, As-Rolled** ### **Product Designation** * **Standard Name:** AISI 1015 / SAE 1015 * **UNS Number:** G10150 * **Condition:** **As-Rolled (Hot-Rolled)** * **Common Forms:** **Sheet, Plate, Bar (Rounds, Flats, Angles), Structural Shapes (I-beams, channels)** * **Key Feature:** The most basic, economical, and widely available supply condition, offering a versatile balance of strength, formability, and weldability directly from the mill. ### **Overview** AISI 1015 in the **as-rolled** condition is the standard, unprocessed form of this fundamental low-carbon steel. It has undergone the hot-rolling process to achieve its final shape and approximate dimensions, but has not received any subsequent thermal treatment (annealing, normalizing) or mechanical processing (cold drawing, grinding). This state provides a cost-effective material with predictable **as-manufactured** properties, characterized by a scaled surface and mechanical properties resulting directly from the rolling temperature and cooling rate. It is the go-to material for general fabrication, construction, and applications where further processing will define the final part. --- ### **1. Chemical Composition (Typical % by Weight, AISI/SAE Standard)** | Element | Content (%) | Role & Effect in As-Rolled State | | :--- | :--- | :--- | | **Carbon (C)** | 0.13 - 0.18 | Provides fundamental strength and hardness. In the as-rolled condition, this carbon level yields a ferrite-pearlite microstructure, giving a good balance of strength and ductility without being brittle. | | **Manganese (Mn)** | 0.30 - 0.60 | Increases strength and hardenability. Influences the transformation during cooling from rolling, affecting final grain structure and properties. | | **Phosphorus (P)** | 0.040 max | Impurity; kept low. | | **Sulfur (S)** | 0.050 max | Impurity; standard level. | | **Iron (Fe)** | Balance | Primary constituent. The microstructure is dominated by ferrite grains with areas of pearlite. | --- ### **2. Physical & Mechanical Properties (As-Rolled Condition)** **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:** Ferromagnetic. **B. Mechanical Properties (Typical)** *Properties can vary based on section size (cooling rate). Thinner sections cool faster and may be slightly stronger.* * **Yield Strength (0.2% Offset):** **275 - 380 MPa (40 - 55 ksi)** * **Tensile Strength:** **400 - 550 MPa (58 - 80 ksi)** * **Elongation in 50 mm:** **20% - 30%** * **Hardness (Brinell):** **110 - 160 HB** * **Surface Finish:** Characteristic dark blue/black, adherent **mill scale**. This oxide layer must be removed for painting, plating, or precision welding. * **Microstructure:** Consists of equiaxed ferrite grains with some pearlite (lamellar structure of ferrite and cementite). The grain size and pearlite fraction depend on the rolling finish temperature and cooling rate. * **Machinability:** **Fair to Good.** Better than lower-carbon steels (1005-1010) due to less gumminess, but the presence of mill scale is abrasive to cutting tools. * **Weldability:** **Excellent.** The low carbon equivalent presents minimal risk of martensite formation in the heat-affected zone (HAZ), preventing cold cracking. Pre-heat is not typically required. --- ### **3. Product Applications** As-rolled AISI 1015 is used in countless applications where its "raw" state is sufficient or where it serves as a starting point for further manufacturing. * **General Fabrication & Structural Components:** * Frames, supports, brackets, guard rails, and base plates. * Structural members in non-critical construction, agricultural equipment, and storage systems. * **Sheet Metal Fabrication:** * Ductwork, enclosures, cabinets, and panels that will be painted or coated after scale removal. * **Forging & Stamping Stock:** * Blanks for hot forging or hot stamping operations. * **Machined Parts (with initial turning/descaling):** * Components like bushings, flanges, and shafts where the first machining operation removes the scaled surface layer. * **Case Hardening Substrate:** * An excellent and economical starting material for parts that will be **carburized or carbonitrided** after rough machining. The as-rolled state is perfectly acceptable for this purpose. * **Wire & Rod for Further Processing:** * Hot-rolled rod intended for subsequent cold drawing into wire or smaller bars. --- ### **4. International Standards & Designations** | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **SAE / AISI (USA)** | **SAE 1015** | The standard designation for the grade. "As-rolled" is the implied default condition unless otherwise specified. | | **UNS (USA)** | **G10150** | Unified Numbering System. | | **ASTM (USA)** | **ASTM A36** (Structural Shapes/Plate), **ASTM A569** (Hot-Rolled Sheet), **ASTM A575** (Merchant Quality Bars) | Commonly supplied to these broad specifications, which govern as-rolled products. | | **DIN / EN (Germany/EU)** | **S235JR (1.0038)** for structurals, **DC01 (1.0330)** for sheet. | **S235JR** is the common "as-rolled" structural steel with similar minimum yield strength. | | **JIS (Japan)** | **SS400** (General Structure), **SPHC** (Hot-Rolled Plate/Sheet) | **SS400** and **SPHC** represent common as-rolled commodity steels. | | **GB (China)** | **Q235B** | The most common Chinese as-rolled structural steel, with a 235 MPa minimum yield strength. | | **ISO** | **ISO 630-2: E235B** | International standard for structural steel in the as-rolled condition. | --- ### **Key Considerations & Processing Notes** 1. **Scale Removal:** The single most important secondary operation. Methods include **abrasive blasting, pickling (acid bath), or flame descaling**. It is essential for corrosion protection, paint adhesion, and quality welding. 2. **Property Variability:** Mechanical properties are not as tightly controlled as in normalized or cold-worked conditions. They represent a *typical range*. 3. **No Stress Relief:** The as-rolled condition contains residual stresses from uneven cooling. For critical machining operations where dimensional stability is paramount, a stress relief anneal may be necessary. 4. **Advantage for Heat Treatment:** For parts destined for carburizing, the as-rolled state is often ideal and most cost-effective, as the full heat treatment cycle will redefine the microstructure. 5. **Economic Benefit:** It is the **lowest-cost form** of AISI 1015, making it the default choice for projects with high material volume or where subsequent processing will account for the surface condition. ### **Summary** **AISI 1015 in the as-rolled condition is the foundational, commodity form of this versatile steel.** It delivers functional mechanical properties, outstanding weldability, and good formability at the absolute minimum cost. Its value lies not in finished precision, but in its role as a reliable and economical raw material for the manufacturing and construction industries. Whether used directly in fabricated structures, as stock for forging, or as the starting point for machined and case-hardened components, as-rolled 1015 provides a predictable and workable base. Its specifications are harmonized with global commodity grades like **ASTM A36, EN S235JR, and GB Q235B**, cementing its status as a universal engineering material. -:- For detailed product information, please contact sales. -: AISI 1015 Steel, as rolled Specification Dimensions Size： Diameter 20-1000 mm Length <4754 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, as rolled Properties -:- For detailed product information, please contact sales. -:
