The cold drawing process involves pulling hot-rolled bars through a carbide die at room temperature, resulting in superior dimensional accuracy, excellent surface finish, and enhanced mechanical properties through strain hardening. AISI 1025, with its moderate carbon content, offers an optimal balance of strength, ductility, and machinability, making this product ideal for applications requiring tight tolerances, good surface quality, and reliable performance with minimal post-processing. --- ## **1. Chemical Composition (Weight %)** AISI 1025 is a medium-carbon steel with a balanced composition that provides good strength while maintaining adequate formability and weldability. | Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Iron (Fe) | |---------|------------|----------------|----------------|------------|-----------| | **Content** | 0.22 – 0.28 | 0.30 – 0.60 | ≤ 0.040 | ≤ 0.050 | Balance | | **Metallurgical Role** | Primary strengthener | Enhances strength & hardenability | Residual element (controlled) | Improves machinability | Base matrix | *Typical Silicon (Si) content: 0.15-0.35% (as a deoxidizer).* --- ## **2. Manufacturing Process & Resultant Properties** **Cold Drawing Process:** Hot-rolled bars are cleaned, phosphate-coated for lubrication, then drawn through progressively smaller carbide dies at room temperature. This cold working induces significant strain hardening, refining the grain structure and improving mechanical properties. **A. Mechanical Properties (Typical, As-Cold-Drawn)** | Property | Value Range | Remarks | |----------|-------------|---------| | **Ultimate Tensile Strength** | 540 – 640 MPa (78 – 93 ksi) | Consistent through diameter range | | **Yield Strength (Rp0.2)** | 480 – 580 MPa (70 – 84 ksi) | 25-35% higher than hot-rolled | | **Elongation (in 50 mm)** | 10 – 15% | Lower than hot-rolled due to work hardening | | **Reduction of Area** | 35 – 45% | | | **Hardness** | 170 – 210 HB (Brinell) | | | **Machinability Rating** | ~70% (relative to 1212 steel) | Good chip formation, requires appropriate tooling | | **Surface Roughness (Ra)** | 1.6 – 3.2 μm (63 – 125 μin) | Superior surface finish | **B. Physical & Dimensional Properties** - **Microstructure:** Elongated ferrite grains with refined pearlite colonies aligned in the drawing direction. - **Dimensional Tolerance:** Typically ±0.08 mm for diameters ≤25 mm, ±0.10 mm for diameters >25 mm (ASTM A108 standards). - **Straightness:** Excellent, typically ≤0.5 mm per meter. - **Density:** 7.85 g/cm³ (0.284 lb/in³). - **Modulus of Elasticity:** 200 GPa (29×10⁶ psi). - **Surface Condition:** Smooth, bright finish with minimal imperfections; typically coated with light oil for corrosion protection. --- ## **3. Typical Applications** Cold-drawn AISI 1025 is widely used in applications requiring precision, strength, and good surface finish with minimal machining. - **Shafts and spindles:** For automotive, industrial machinery, and power transmission systems. - **Precision fasteners:** High-strength bolts, studs, and special threaded components. - **Hydraulic components:** Piston rods, cylinder barrels, valve stems for medium-pressure systems. - **Automotive components:** Axle shafts, steering components, transmission parts. - **General machined parts:** Bushings, couplings, pins, and spacers requiring tight tolerances. - **Tooling components:** Guide pins, ejector pins, and fixture elements. - **Agricultural equipment:** Implement shafts and linkage components. --- ## **4. Conforming International Standards** This product meets requirements of multiple international standards for cold-finished steel bars. | Standard System | Standard Number | Equivalent Designation | Scope / Notes | |----------------|----------------|------------------------|---------------| | **UNS/SAE/AISI** | G10250 | AISI/SAE 1025 | Base material specification | | **ASTM (USA)** | **ASTM A108** | Grade 1025 | Standard for cold-finished carbon steel bars | | **ASTM** | ASTM A29/A29M | Grade 1025 | General specification (cold-finished condition) | | **ISO (International)** | ISO 683-1 | 1.1158 | Non-alloy steels for heat treatment | | **EN (Europe)** | EN 10083-2 | C25E (1.1158) | Steels for quenching and tempering | | **JIS (Japan)** | JIS G4051 | S25C | Carbon steels for machine structural use | | **DIN (Germany)** | DIN 17200 | C25 | Case-hardening and heat-treatable steels | | **GB (China)** | GB/T 699 | 25# | Comparable grade | --- ## **5. Key Advantages** - **Superior Dimensional Accuracy:** Tight tolerances reduce machining allowance and material waste. - **Excellent Surface Finish:** Smooth surface reduces friction and improves appearance. - **Enhanced Mechanical Properties:** Cold working significantly increases yield and tensile strength. - **Good Straightness:** Ideal for automated machining and feeding systems. - **Consistent Quality:** Uniform properties throughout length and between batches. - **Versatile Processability:** Suitable for machining, grinding, and moderate cold forming. - **Excellent Response to Heat Treatment:** Ideal for case hardening, induction hardening, and through-hardening. --- ## **6.

Comparison with Similar Grades** | Property | AISI 1025 (Cold-Drawn) | AISI 1020 (Cold-Drawn) | AISI 1030 (Cold-Drawn) | |----------|------------------------|------------------------|------------------------| | **Carbon Content** | 0.22-0.28% | 0.18-0.23% | 0.28-0.34% | | **Tensile Strength** | 540-640 MPa | 500-600 MPa | 560-660 MPa | | **Machinability** | Good | Very Good | Fair | | **Weldability** | Good | Excellent | Fair | | **Case Hardening Response** | Excellent | Very Good | Good | | **Cost** | Moderate | Lower | Higher | **Note:** The 19-32 mm diameter range represents an optimal balance between cold drawability and property uniformity for AISI 1025. For applications requiring specific mechanical properties beyond the typical cold-drawn condition, heat treatment can be specified. This product is particularly well-suited for components that will undergo subsequent case hardening or induction hardening processes, as the cold-drawn condition provides an excellent, uniform substrate for such treatments. -:- For detailed product information, please contact sales. -: AISI 1025 Steel, cold drawn, 19-32 mm (0.75-1.25 in) round Specification Dimensions Size： Diameter 20-1000 mm Length <5484 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 1025 Steel, cold drawn, 19-32 mm (0.75-1.25 in) round Properties -:- For detailed product information, please contact sales. -:
