AISI 1010 Steel, CQ sheet,1.6-5.8 mm round or thickness Product Information -:- For detailed product information, please contact sales. -: ## **Product Specification: AISI 1010 Low Carbon Steel, Commercial Quality Sheet** ### **Product Designation** * **Standard Name:** AISI 1010 (Base Grade) * **Quality Designation:** **Commercial Quality (CQ)** * **UNS Number:** G10100 * **Product Form:** **Sheet** * **Thickness Range:** **1.6 mm to 5.8 mm (0.06 inch to 0.23 inch)** * **Surface:** Standard mill finish, typically with a light oxide layer. * **Key Feature:** A cost-effective, general-purpose steel sheet for applications where high formability is not required, and surface finish is secondary to function and cost. ### **Overview** AISI 1010 Commercial Quality (CQ) sheet steel is the most economical and basic form of 1010 steel within the specified thickness range. Produced with standard deoxidation practices (often rimmed or capped), CQ sheet prioritizes manufacturability and low cost over exceptional formability or surface perfection. It is suitable for a wide range of general fabrication applications involving bending, light forming, welding, and painting where the presence of minor surface imperfections is acceptable. This product is the workhorse of industrial sheet metal for non-critical structural and enclosure components. --- ### **1. Chemical Composition (Typical % by Weight, CQ Practice)** The composition follows standard AISI 1010 ranges, with less stringent control than Drawing Quality (DQ) grades. | Element | Content (%) | Role & Effect in CQ Sheet | | :--- | :--- | :--- | | **Carbon (C)** | 0.08 - 0.13 | Provides basic strength. Slightly higher than 1008 CQ, offering better stiffness. | | **Manganese (Mn)** | 0.30 - 0.60 | Standard range for strength and deoxidation. | | **Phosphorus (P)** | 0.040 max | Impurity; standard control. | | **Sulfur (S)** | 0.050 max | Impurity; standard control. | | **Silicon (Si)** | Typically low (<0.10) | Minimized in rimmed/capped steel to ensure a good surface for painting, but not as controlled as in killed steels. | | **Note:** CQ steel is not fully deoxidized (killed), which can lead to more variability in properties and a potential for **strain aging** (increase in yield strength and loss of ductility over time after cold working). | --- ### **2. Physical & Mechanical Properties (CQ Sheet, 1.6-5.8 mm thick)** **A. Physical Properties** * **Density:** 7.87 g/cm³ * **Elastic Modulus (E):** 200 GPa (29,000 ksi) * **Thermal Conductivity:** High (~61 W/m·K) * **Magnetic Properties:** Strongly ferromagnetic. **B. Mechanical Properties (Typical, As-Rolled)** | Property | **Commercial Quality (CQ) - AISI 1010** | | :--- | :--- | | **Yield Strength** | 210 - 310 MPa (30 - 45 ksi) | | **Tensile Strength** | 340 - 430 MPa (49 - 62 ksi) | | **Elongation in 50 mm** | **20% - 30%** (Adequate for simple bends and light forming) | | **Hardness (Brinell)** | 105 - 145 HB | | **n-value (Strain Hardening Exponent)** | Lower, more variable. Not optimized for stretch forming. | | **r-value (Plastic Strain Ratio)** | Lower, variable. Not optimized for deep drawing. | | **Surface Finish** | Standard mill finish. May exhibit minor imperfections like roll marks, scale, or slight roughness. Suitable for painting after proper cleaning/prep. | | **Formability** | **Fair.** Suitable for **simple bends, roll forming, and flanging.** Not recommended for deep drawing or severe stretching operations. | | **Strain Aging** | **Prone to aging.** May become slightly harder and more brittle over time after cold working. | --- ### **3. Product Applications** AISI 1010 CQ sheet is specified for applications where function, weldability, and low cost are the primary drivers. * **General Fabrication & Enclosures:** * Electrical cabinets, control boxes, and junction boxes. * Machine guards, covers, and shrouds. * Ductwork and ventilation housings. * **Structural & Support Components:** * Brackets, mounting plates, frames, and shelving. * Trailer side panels and flooring (non-structural). * **Agricultural & Industrial Equipment:** * Covers, chutes, and hoppers for farming equipment. * Covers for industrial machinery. * **Painted Assemblies:** * Parts where the surface will be cleaned, primed, and painted, hiding minor imperfections. * **Non-Critical Automotive Parts:** * Internal brackets, shields, and reinforcements not visible in the final assembly. --- ### **4. International Standards & Designations** | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **ASTM (USA)** | **ASTM A366** | **The standard specification for Commercial Quality (CQ) carbon steel sheet.** | | **SAE / AISI** | **SAE 1010** with CQ practice | Quality is defined by the purchase specification (ASTM A366). | | **DIN / EN (EU)**| **DC01 (EN 10130)** | The closest European equivalent for cold-rolled, mild forming steel sheet. DC01 is considered a "Commercial Quality" grade. | | **JIS (Japan)** | **SPCC (JIS G3141)** | The Japanese standard for cold-rolled carbon steel sheets, equivalent to Commercial Quality. | | **GB (China)** | **SPCC (GB/T 5213)** | Adopts the JIS nomenclature; a direct equivalent. | | **ISO** | **ISO 3574: CR2 (Commercial Quality)** | International classification for cold-rolled carbon steel sheet. | --- ### **Selection Guide & Processing Notes** 1. **When to Specify CQ:** Choose CQ when the part design involves **simple shapes, bends, and welds**, the **surface will be painted**, and **cost is a critical factor**. It is not for exposed, decorative, or highly formed parts. 2. **Forming Limitation:** Avoid deep draws or complex stretch forms. The lower and more variable ductility can lead to cracking or inconsistent springback. 3. **Welding:** **Excellent.** Standard welding practices apply. No pre-heat or post-heat treatment required. 4. **Painting Preparation:** The surface **must be properly cleaned** (degreased, de-scaled via abrasive blasting or chemical treatment) to ensure paint adhesion. 5. **Strain Aging:** For parts that are cold-formed and must remain dimensionally stable over time (e.g., a flat bracket), be aware that slight distortion or hardening could occur over weeks/months. For such applications, a killed steel (DQ or DQSK) is preferred. ### **Summary** **AISI 1010 Commercial Quality (CQ) sheet (1.6-5.8 mm thick) is the economical, no-frills workhorse of the sheet metal world.** It delivers the essential properties of mild steel—weldability, basic formability, and adequate strength—at the lowest possible cost. Its use is justified in a vast array of industrial and agricultural fabrications where the part is functional rather than cosmetic, and where manufacturing processes are straightforward. Specifying CQ under **ASTM A366** (or its global equivalents like **EN DC01** and **JIS SPCC**) ensures a predictable, fit-for-purpose material that maximizes value in non-critical applications. -:- For detailed product information, please contact sales. -: AISI 1010 Steel, CQ sheet,1.6-5.8 mm round or thickness Specification Dimensions Size： Diameter 20-1000 mm Length <4745 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 1010 Steel, CQ sheet,1.6-5.8 mm round or thickness Properties -:- For detailed product information, please contact sales. -:
