AISI 1065 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: AISI 1065 Steel, Hot Rolled Round Bar (19-32 mm / 0.75-1.25 in)** **Overview** AISI 1065 is a high-carbon, non-alloy steel known for its excellent strength, hardness, and wear resistance in the heat-treated condition. Supplied in the form of hot-rolled round bars within the 19-32 mm (0.75-1.25 in) diameter range, this product offers a good balance of machinability (in the annealed state) and final performance after thermal processing. It is a versatile and cost-effective material for applications requiring high mechanical properties and durability. --- #### **1. Chemical Composition** The composition is key to the performance of AISI 1065. The following table outlines the standard percentage ranges by weight. | Element | Content (%) | | :--- | :--- | | **Carbon (C)** | 0.60 - 0.70 | | **Manganese (Mn)** | 0.60 - 0.90 | | **Phosphorus (P)** | ≤ 0.040 | | **Sulfur (S)** | ≤ 0.050 | | **Iron (Fe)** | Balance | **Note:** The high carbon content is the primary contributor to its hardenability and strength. --- #### **2. Typical Physical & Mechanical Properties (As-Hot Rolled)** *Hot-rolled bars have a characteristic mill scale on the surface and possess properties prior to any further heat treatment.* | Property | Typical Value / Description | | :--- | :--- | | **Density** | 7.85 g/cm³ (0.284 lb/in³) | | **Modulus of Elasticity** | 190-210 GPa (27,500-30,500 ksi) | | **Tensile Strength** | 625 - 725 MPa (90 - 105 ksi) | | **Yield Strength (0.2% Offset)** | 370 - 415 MPa (54 - 60 ksi) | | **Elongation (in 50 mm)** | ~ 12-15% | | **Hardness (Brinell)** | 187 - 229 HB | | **Machinability (Compared to AISI 1212)** | ~ 60% (Better after annealing) | --- #### **3. Key Characteristics & Heat Treatment Response** * **High Hardenability:** Responsive to quenching and tempering, achieving high surface and core hardness. * **Wear Resistance:** Excellent after hardening, suitable for parts subject to abrasion. * **Spring Properties:** A premier choice for manufacturing mechanical springs and clutch plates due to its high elastic limit. * **Formability & Weldability:** Fair in the annealed state; welding requires preheating and post-weld heat treatment due to high carbon content to avoid cracking. Not typically recommended for general welding. **Common Heat Treatment:** * **Annealing:** Heated to ~790°C (1450°F) and slowly cooled to soften for machining. * **Quenching & Tempering:** Heated to ~800-830°C (1475-1525°F), quenched in oil or water, and then tempered at a selected temperature (e.g., 200-400°C / 400-750°F) to achieve desired hardness and toughness. --- #### **4. Product Applications** AISI 1065 round bars in this medium diameter range are widely used in the manufacturing of high-strength components, including: * **Springs:** Leaf springs for automotive suspensions, coil springs, and spring washers. * **Hand Tools:** Wrenches, crowbars, screwdrivers, and agricultural tools. * **Cutting Blades:** For lawn mowers, industrial cutting knives (after proper heat treatment). * **Shafts & Axles:** Light-duty axles, pins, and mandrels requiring wear resistance. * **Clutch Plates & Discs:** For automotive and machinery applications. * **Wear Parts:** Chain links, scraper blades, and grader blades. --- #### **5. Relevant International & Industry Standards** AISI 1065 is specified under various international standards with equivalent grades. | Standard | Equivalent Designation | Form / Specification | | :--- | :--- | :--- | | **AISI / SAE (USA)** | **1065** | Standard Carbon Steel | | **ASTM (USA)** | **A29/A29M** | Standard Specification for Steel Bars, Carbon and Alloy | | **UNS (USA)** | **G10650** | Unified Numbering System | | **DIN (Germany)** | **1.0603 / C66** | - | **JIS (Japan)** | **SWRH67A / SWRH67B** | (For wire rod, similar composition) | | **GB (China)** | **65#** | (Similar grade, GB/T 699) | **Note:** The hot-rolled round bar form typically conforms to dimensional tolerances specified in standards like **ASTM A29** for Hot-Wrought Carbon Steel Bars. --- #### **6. Available Forms & Finishes** * **Form:** Round bars, hot-rolled. * **Size Range:** 19 mm to 32 mm (0.75 in to 1.25 in) diameter. * **Standard Lengths:** Typically 3m, 6m (10ft, 20ft), or cut to order. * **Surface Condition:** Black hot-rolled with mill scale. Can be further processed by peeling, turning, or grinding for precise dimensions and smoother finish. --- **Summary** AISI 1065 hot-rolled round bar is a fundamental high-carbon steel product ideal for fabricators who perform subsequent heat treatment to develop high strength, hardness, and wear resistance. Its availability in the 19-32 mm diameter range makes it a popular choice for a wide array of automotive, tooling, and industrial components where durability and performance are critical. -:- For detailed product information, please contact sales. -: AISI 1065 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <4861 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 1065 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Properties -:- For detailed product information, please contact sales. -:
