AISI 1034 Steel Product Information -:- For detailed product information, please contact sales. -: ### **Technical Data Sheet: AISI 1034 Steel** --- #### **1. Material Overview** AISI 1034 is a medium-carbon, non-alloy steel belonging to the 10xx series of standard carbon steels. It is characterized by a balanced carbon-manganese composition that provides good tensile strength, reasonable ductility, and favorable hardenability for general engineering applications. As a versatile and economical material, AISI 1034 can be supplied in various conditions including hot-rolled, cold-drawn, normalized, or heat-treated states to meet specific performance requirements across multiple industries. --- #### **2. Key Characteristics** - **Good Strength-to-Toughness Balance**: Suitable for moderately stressed components - **Favorable Hardenability**: Responds well to heat treatment processes - **Cost-Effective**: Widely available as a standard carbon steel grade - **Machinable**: Can be machined effectively with proper tooling and conditions - **Weldable with Precautions**: Requires appropriate procedures due to medium carbon content --- #### **3.

Mechanical Properties** *Properties vary significantly with processing condition. Below are typical ranges:* | Condition | Tensile Strength | Yield Strength | Elongation (%) | Hardness (HB) | |-----------|------------------|----------------|----------------|---------------| | **Hot-Rolled** | 510-620 MPa (74-90 ksi) | 345-450 MPa (50-65 ksi) | 15-20 | 149-197 | | **Cold-Drawn** | 550-690 MPa (80-100 ksi) | 480-550 MPa (70-80 ksi) | 10-15 | 179-229 | | **Normalized** | 520-630 MPa (75-91 ksi) | 360-470 MPa (52-68 ksi) | 18-22 | 156-207 | | **Quenched & Tempered** | 860-1100 MPa (125-160 ksi) | 690-950 MPa (100-138 ksi) | 12-18 | 248-302 | *Additional Properties:* - **Modulus of Elasticity**: 200 GPa (29,000 ksi) - **Poisson's Ratio**: 0.29 - **Density**: 7.87 g/cm³ (0.284 lb/in³) - **Machinability**: ~60% (relative to 1212 steel) --- #### **5. International Standard Equivalents** | Standard System | Designation | Specification | |-----------------|-------------|---------------| | **UNS** | G10340 | Unified Numbering System | | **SAE/AISI** | 1034 | SAE J403 | | **ASTM** | Grade 1034 | ASTM A29, A576 | | **EN (Europe)** | 1.1151 (C35E) | EN 10083-2 | | **ISO** | C35E | ISO 683-18 | | **JIS (Japan)** | S35C | JIS G4051 | | **GB (China)** | 35# | GB/T 699 | | **DIN (Germany)** | 1.1151, Ck35 | DIN 17200 | --- #### **6. Heat Treatment Guidelines** **Annealing**: Heat to 790-815°C (1450-1500°F), furnace cool to 540°C (1000°F), then air cool **Normalizing**: Heat to 870-925°C (1600-1700°F), air cool **Quenching**: Austenitize at 830-855°C (1525-1575°F), quench in oil or water (oil preferred for complex shapes) **Tempering**: Temper at 400-650°C (750-1200°F) based on desired hardness and strength **Surface Hardening**: Suitable for flame or induction hardening processes --- #### **7. Primary Applications** AISI 1034 steel serves diverse industries due to its balanced properties: **Automotive & Transportation:** - Axle shafts and drive components - Gears and pinions (after heat treatment) - Connecting rods and crankshafts - Suspension components **Industrial Machinery:** - General purpose shafts and spindles - Machine tool components - Hydraulic cylinder rods - Fasteners and studs (high-strength applications) **Agricultural Equipment:** - Implement shafts - Tractor components - Plow shares and cultivator parts **Construction & Mining:** - Bucket teeth and cutting edges - Drill rods and tooling - Heavy-duty pins and bushings **General Manufacturing:** - Die blocks and tool holders - Press frames and structural components - Wear plates and guides --- #### **8. Fabrication & Processing** **Machining:** - Use sharp, positive rake tools with adequate clearance - Moderate cutting speeds with ample coolant flow - Chip breakers recommended for continuous machining - Annealed condition provides optimal machinability **Welding:** - Pre-heat to 150-260°C (300-500°F) for sections >6 mm (0.25 in) - Use low-hydrogen electrodes (E7018, E8018) - Post-weld heat treatment recommended (595-650°C / 1100-1200°F) - Limit heat input to minimize HAZ hardness **Forming:** - Good cold forming characteristics in annealed condition - Hot forming recommended for complex shapes - Minimum bend radii: 1-2 times material thickness --- #### **9. Quality & Inspection** - Standard mill test reports available (chemical analysis, mechanical properties) - Non-destructive testing options: ultrasonic, magnetic particle, dye penetrant - Dimensional tolerances per applicable ASTM standards - Surface conditions: hot-rolled (mill scale), cold-drawn (bright), or specially prepared --- **Important Considerations:** 1. Material selection should consider required strength level, section size, and heat treatment capabilities 2. Quench cracks may occur with water quenching of complex shapes; oil quenching is generally preferred 3. Stress relieving (550-650°C / 1020-1200°F) recommended after heavy machining operations 4. For critical applications, specify additional requirements: Charpy impact testing, hardenability bands, or special cleanliness 5. Always consult material specifications and conduct application-specific testing for performance validation --- **Disclaimer:** This technical data sheet provides general information about AISI 1034 steel.
