AISI 1026 Steel, cold drawn, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: ### **Technical Data Sheet: AISI 1026 Cold Drawn Steel Round Bars (19-32 mm / 0.75-1.25 in)** --- #### **1. Product Overview** AISI 1026 cold drawn steel rounds represent a medium-carbon, cold-finished steel product offering superior dimensional accuracy, enhanced surface finish, and increased mechanical strength compared to hot-rolled equivalents. The cold drawing process involves pulling hot-rolled bars through a die at room temperature, resulting in precise dimensions, improved straightness, and a smooth, scale-free surface. The 19-32 mm (0.75-1.25 in) diameter range is widely utilized for precision components requiring consistent performance without extensive secondary machining. --- #### **2. Key Characteristics & Advantages** * **Enhanced Strength & Hardness:** The cold working process increases tensile and yield strength through strain hardening, providing greater load-bearing capacity than hot-rolled 1026. * **Superior Dimensional Accuracy:** Cold drawing produces tight diameter tolerances, typically within ±0.075 mm (±0.003 in), ensuring excellent fit and interchangeability. * **Excellent Surface Finish:** The process yields a smooth, bright surface (approximately 1.6-3.2 μm Ra or 63-125 μin Ra), free of mill scale, reducing friction and improving appearance. * **Improved Straightness:** Ideal for applications requiring precise alignment and minimal runout. * **Good Machinability & Weldability:** Despite increased strength, it maintains favorable machinability for a medium-carbon steel and can be welded with standard procedures (pre-heat may be recommended for thicker sections). --- #### **3.

Primary Applications** Cold drawn AISI 1026 rounds are specified for mechanical components requiring precise dimensions, good strength, and reliable performance: * **Automotive & Transportation:** * Axle shafts and stub shafts * Gear blanks and transmission components * Steering linkage parts * **General Machinery:** * Hydraulic piston rods and cylinders * Shafts for motors and pumps * Fasteners and precision bolts (Grade 8.8 equivalents) * **Manufacturing Equipment:** * Guide rods and linear shafts * Spindles and arbors * * Jig and fixture components * **Construction & Agriculture:** * Pivot pins and bushings * Implement shafts * Connecting rods (non-critical applications) * **Consumer Products:** * Bicycle components * Hardware and tool parts --- #### **7. Processing & Fabrication Notes** * **Machinability:** Good (approximately 55-60% of 1212 steel reference); responds well to modern cutting tools and coolants. * **Weldability:** Fair to good; pre-heating (150-260°C / 300-500°F) and post-weld stress relief are recommended for optimal results, especially in constrained applications. * **Heat Treatment:** Can be normalized, annealed, or through-hardened by quenching and tempering to achieve higher strength levels. Suitable for flame or induction hardening of specific wear surfaces. * **Cold Working:** Excellent response to bending, swaging, and other forming operations within reasonable strain limits. * **Straightness Tolerance:** Typically ≤ 0.4 mm per 300 mm (0.015 in per foot). --- #### **8. Quality Assurance** Material supplied to ASTM A108 includes certification providing: * Heat analysis chemical composition * Mechanical property verification * Dimensional inspection report * Surface condition verification * Optional non-destructive testing (ultrasonic, magnetic particle) available upon request --- **Note:** Properties may vary between manufacturers and heat lots. Cold drawn bars exhibit some directionality in properties (anisotropy). For critical applications requiring maximum toughness, consider stress relieving after machining or specify annealed condition prior to severe cold forming. Always consult the manufacturer's certified test reports for project-specific validation. -:- For detailed product information, please contact sales. -: AISI 1026 Steel, cold drawn, 19-32 mm (0.75-1.25 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <4785 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 1026 Steel, cold drawn, 19-32 mm (0.75-1.25 in) round Properties -:- For detailed product information, please contact sales. -:
