AISI 1026 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: ### **Product Technical Specification: AISI 1026 Hot Rolled Steel Round Bars (19-32 mm / 0.75-1.25 in)** --- #### **1. Product Overview** AISI 1026 hot rolled round bars represent a medium-carbon, non-alloy steel supplied in the as-rolled condition with characteristic mill scale surface. With a balanced carbon-manganese composition, this material provides enhanced strength over 1025 steel while maintaining good weldability and formability. The 19-32 mm (0.75-1.25 in) diameter range offers optimal versatility for general structural and mechanical applications requiring moderate strength and reliable performance at economical cost. --- #### **2. Key Characteristics & Advantages** * **Balanced Strength & Toughness:** Higher manganese content provides improved hardenability and strength compared to 1025 steel while retaining adequate ductility * **Good Formability:** Suitable for moderate bending, forging, and other hot-working operations * **Economical Production:** Hot rolling represents the most cost-effective production method for steel bars * **Versatile Weldability:** Can be welded using common methods with proper precautions (pre-heating recommended for thicker sections) * **Favorable Machinability:** Offers reasonable machining characteristics in normalized or hot-rolled condition * **Through-Hardenable Capability:** Can be effectively heat treated by quenching and tempering for increased strength applications --- #### **3.

Primary Applications** Hot rolled AISI 1026 rounds are extensively used in general manufacturing and construction where strength requirements exceed those of lower-carbon steels: * **Construction & Infrastructure:** * Anchor bolts and foundation fasteners * Structural connectors and brackets * Reinforcing components for machinery bases * **General Manufacturing:** * Shafts for industrial equipment * Gears, sprockets, and pinions (after heat treatment) * Axles and spindle components * **Transportation Equipment:** * Truck and trailer components * Agricultural implement parts * Railroad components (non-critical) * **Forging Stock:** * Preforms for closed-die forgings * Blank material for upset forgings * Billet stock for further processing * **Machinery Components:** * Bolts, studs, and threaded rods (Grade 5.8-8.8 equivalents) * Hydraulic cylinder barrels * General welded fabrications * **Agricultural Equipment:** * Plow shares and cultivator components * Implement frames and supports * PTO shafts and drive components --- #### **7. Processing & Fabrication Notes** * **Machinability:** Good (approximately 60% of 1212 steel reference) in hot-rolled condition; improves with annealing * **Weldability:** Fair to good; pre-heating (150-200°C / 300-400°F) recommended for sections over 12 mm (0.5 in) and post-weld stress relief advised for critical applications * **Heat Treatment:** Responds well to normalizing, annealing, and quenching/tempering processes * Annealing: Heat to 845-900°C (1550-1650°F), slow cool * Normalizing: Heat to 870-925°C (1600-1700°F), air cool * Quenching: Heat to 830-855°C (1525-1575°F), quench in oil or water * Tempering: 425-650°C (800-1200°F) depending on desired hardness * **Forming:** Can be hot-worked at 1150-1260°C (2100-2300°F); cold forming possible with appropriate bend radii * **Surface Preparation:** Mill scale should be removed by pickling, abrasive blasting, or machining for painting, plating, or precision applications --- #### **8. Quality Assurance** Material certification typically includes: * Heat/lot chemical analysis * Mechanical property test results * Dimensional inspection report * Compliance statement with ASTM A29/A576 or equivalent standards * Optional Charpy impact testing available upon request --- **Note:** Properties listed are typical for hot-rolled condition and may vary between manufacturers and production batches. For applications requiring consistent mechanical properties or specific heat treatment conditions, consultation with material engineers is recommended. Mill scale removal is necessary for most finishing operations and critical welding applications. -:- For detailed product information, please contact sales. -: AISI 1026 Steel, hot rolled, 19-32 mm (0.75-1.25 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <4786 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, hot rolled, 19-32 mm (0.75-1.25 in) round Properties -:- For detailed product information, please contact sales. -:
