AISI 1110 Steel Composition Spec (UNS G11100) Product Information -:- For detailed product information, please contact sales. -: ### **Product Data Sheet: AISI 1110 Steel Composition Specification (UNS G11100)** #### **1. Overview** AISI 1110 (UNS G11100) is a low-carbon, non-resulfurized manganese steel. As a composition specification, it defines a material with slightly higher carbon and manganese content than the most basic low-carbon steels (e.g., 1008, 1010). This combination provides a balanced profile of **good formability, fair machinability, and a moderate response to work hardening and case hardening**. It is commonly used as a general-purpose, low-cost steel for parts that require a combination of light forming and machining, and can serve as a core material for carburized components where a tougher, stronger base than 1010 is desired. --- #### **2. Chemical Composition (AISI/SAE Standard)** | Element | Content (%) | | :--- | :--- | | **Carbon (C)** | 0.08 - 0.13 | | **Manganese (Mn)** | **0.30 - 0.60** | | **Phosphorus (P)** | ≤ 0.040 | | **Sulfur (S)** | ≤ 0.050 | | **Iron (Fe)** | Balance | **Key Distinction:** Compared to AISI 1010 (Mn: 0.30-0.60%), the carbon range is identical. The primary difference from the **1108** grade is the **absence of added sulfur** for free-machining properties. Compared to **1015**, it has a slightly lower carbon upper limit. --- #### **3. Typical Physical & Mechanical Properties** *Properties vary significantly based on processing condition (hot-rolled, cold-drawn, annealed). Below are representative ranges.* | Property / Condition | Hot-Rolled (As-Rolled) | Cold-Drawn / Work-Hardened | Annealed (Soft) | | :--- | :--- | :--- | :--- | | **Tensile Strength** | 365 - 460 MPa (53 - 67 ksi) | 420 - 550 MPa (61 - 80 ksi) | 320 - 400 MPa (46 - 58 ksi) | | **Yield Strength** | 200 - 295 MPa (29 - 43 ksi) | 350 - 480 MPa (51 - 70 ksi) | 180 - 250 MPa (26 - 36 ksi) | | **Elongation (in 50mm)** | ~ 25 - 35% | ~ 15 - 22% | ~ 30 - 40% | | **Hardness (Approx.)** | ~ 100-130 HB | ~ 120-160 HB | ~ 90-110 HB | | **Machinability** | Fair (~70% of AISI 1212) | Fair to Good | Fair (softer but gummier) | | **Primary Characteristic** | Low cost, good formability. | Increased strength, better finish/tolerance. | Maximum ductility for severe forming. | **General Characteristics:** * **Density:** 7.87 g/cm³ * **Modulus of Elasticity:** 190-205 GPa (28,000-29,700 ksi) * **Hardenability:** Very low. Not suitable for through-hardening (quenching & tempering). **Excellent candidate for case hardening** (e.g., carburizing, carbonitriding) due to low core carbon content. * **Weldability:** **Excellent.** Low carbon equivalent makes it highly weldable by all common processes with minimal pre-heat. --- #### **4. Key Characteristics & Metallurgical Behavior** * **Good Formability and Weldability:** The low carbon content ensures high ductility and excellent weldability, making it suitable for fabricated structures and formed parts. * **Non-Free-Machining:** Unlike the 11xx series with sulfur (e.g., 1108, 1117), AISI 1110 does not contain added sulfur for chip breaking. Machinability is standard for a low-carbon steel and is less than that of free-machining grades. * **Response to Cold Work:** Readily work hardens during cold forming or drawing, which can be used to increase its strength. * **Ideal for Case Hardening:** Its low core carbon provides a tough and ductile substrate, while the surface can be enriched with carbon (carburized) and hardened to create a wear-resistant component with a resilient core. --- #### **5. Typical Product Applications** AISI 1110 is used for a wide variety of low-stress, general engineering components. * **Cold Formed & Headed Parts:** Nuts, bolts, rivets, clips, and other fasteners or small stampings. * **Structural & Fabricated Components:** Light brackets, frames, and supports where weldability is important. * **Shafts & Pins for Light Duty:** Non-critical axles, rollers, and hinge pins. * **Case Hardened Components:** Gears, pins, camshafts, and other parts that are carburized or carbonitrided to achieve a hard, wear-resistant surface over a tough core. (Often specified as **1110 Carburizing Grade**). * **General Machined Parts:** Where machinability is not the sole critical factor and parts will be case hardened or used as-is for low-strength applications. --- #### **6. Relevant International & Industry Standards** | Standard System | Standard Designation | Title / Scope (Relevant to this Product Form) | | :--- | :--- | :--- | | **AISI / SAE / UNS (USA)** | **1110, SAE J403, UNS G11100** | Standard Grade Designation | | **ASTM (USA)** | **ASTM A29/A29M** | Specification for Steel Bars, Carbon and Alloy, Hot-Wrought and Cold-Finished | | **ASTM (USA)** | **ASTM A510** | Specification for General Requirements for Wire Rods and Coarse Round Wire | | **ASTM (USA)** | **ASTM A576** | Specification for Steel Bars, Carbon, Hot-Wrought, Special Quality | | **DIN / EN (Germany/EU)** | **1.1121 / C10E / C10R** | EN 10083-1 / 10084: Steel for quenching and tempering / Case hardening steels. | | **JIS (Japan)** | **SUM12? / S10C** | Free-cutting steel equivalent not direct. For case hardening: **S10C** (JIS G4051). | | **GB (China)** | **10#** | Quality Carbon Structural Steel (GB/T 699). | --- ### **Processing & Selection Notes** 1. **Condition Selection:** Choose the product form (hot-rolled, cold-drawn, annealed) based on the initial fabrication method (forming vs. machining) and required strength. 2. **Case Hardening Pathway:** For wear applications: Machine/Form -> Carburize -> Quench & Temper (low temperature) -> Finish Grind. 3. **Machining Consideration:** For parts requiring extensive machining, a free-machining grade like **1117** (resulfurized) or **12L14** (leaded) would be more economical. 4. **Direct Replacement:** Often interchangeable with **AISI 1010, 1015**, with minor variations in properties. **1018** offers higher manganese for slightly better hardenability if needed. **Summary:** **AISI 1110 (UNS G11100) is a versatile, low-carbon, non-alloy steel specification.** It serves as a **general-purpose workhorse material** valued for its good formability, excellent weldability, and suitability for case hardening. Its applications bridge simple formed parts and more durable case-hardened components. While not specialized for maximum machinability or strength, it offers a reliable and cost-effective balance of properties for a wide range of low-to-moderate duty engineering applications. -:- For detailed product information, please contact sales. -: AISI 1110 Steel Composition Spec (UNS G11100) Specification Dimensions Size： Diameter 20-1000 mm Length <4923 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 1110 Steel Composition Spec (UNS G11100) Properties -:- For detailed product information, please contact sales. -:
