AISI 1075 Carbon Steel Bar Product Information -:- For detailed product information, please contact sales. -: ### **Product Data Sheet: AISI 1075 Carbon Steel Bar** #### **1. Overview** AISI 1075 is a high-carbon, non-alloy steel widely recognized for its exceptional **strength, hardness, and wear resistance potential** after heat treatment. Supplied in various bar forms (hot-rolled, cold-drawn, annealed), it is a premier choice for applications demanding high elastic limit and durability. Its high carbon content provides excellent hardenability, making it particularly renowned as a **spring steel**, but its utility extends to a broad range of tooling and wear components. AISI 1075 offers an optimal balance between extreme performance and cost-effectiveness for high-strength parts. --- #### **2. Chemical Composition (AISI/SAE Standard)** The precise chemistry defines its core characteristics. | Element | Content (%) | | :--- | :--- | | **Carbon (C)** | **0.70 - 0.80** | | **Manganese (Mn)** | 0.60 - 0.90 | | **Phosphorus (P)** | ≤ 0.040 | | **Sulfur (S)** | ≤ 0.050 | | **Silicon (Si)** | 0.15 - 0.35 | | **Iron (Fe)** | Balance | **Note:** The carbon range places AISI 1075 in the same category as **1078/1080**, making them largely interchangeable for most applications. --- #### **3. Typical Physical & Mechanical Properties** *Properties vary significantly based on condition (as-rolled, cold-drawn, annealed, heat-treated).* | Property | Condition: Hot-Rolled (As-Supplied) | Condition: Quenched & Tempered (Hardened) | Condition: Spheroidized Annealed (For Forming) | | :--- | :--- | :--- | :--- | | **Tensile Strength** | 650 - 800 MPa (94 - 116 ksi) | **1150 - 1550+ MPa (167 - 225+ ksi)** | 520 - 620 MPa (75 - 90 ksi) | | **Yield Strength** | 360 - 450 MPa (52 - 65 ksi) | **1000 - 1400+ MPa (145 - 203+ ksi)** | 415 - 550 MPa (60 - 80 ksi) | | **Elongation** | ~ 10 - 15% | **Very Low (<5%)** | ≥ 12% | | **Hardness** | 190 - 240 HB | **55 - 65 HRC** | 75 - 88 HRB | | **Primary Feature** | Good machinability; ready for forging. | **Maximum wear resistance & strength.** | **Maximum ductility for cold forming.** | --- #### **4. Key Characteristics & Metallurgical Behavior** * **Exceptional Hardenability:** Responds robustly to quenching (in oil or water) and tempering, achieving very high surface and core hardness. Care must be taken to avoid quench cracking due to high carbon content. * **High Elastic Limit:** This is its defining trait for spring applications. It can withstand significant repeated deflection without permanent deformation (when properly heat-treated to a spring temper, typically ~45-52 HRC). * **Wear Resistance:** In the hardened state, it offers superior resistance to abrasion and galling. * **Machinability & Formability:** Fair in the as-rolled state; good in the annealed state. For severe cold forming (e.g., cold heading), a **spheroidized annealed** condition is mandatory. * **Weldability:** **Very Poor.** Not recommended for welding due to extreme risk of cracking in the heat-affected zone. If unavoidable, requires stringent pre-heat, post-heat, and specialized filler metals. --- #### **5. Primary Product Applications** AISI 1075 bars are foundational material for high-performance components. * **Springs (Primary Application):** * **Coil Springs:** Heavy-duty valve springs, clutch springs, suspension springs. * **Flat Springs:** Leaf springs (automotive/truck), cantilever springs, snap rings. * **Torsion Bars.** * **Cutting Tools & Blades:** * Industrial knives, scrapers, mower blades, hand tools (chisels, punches). * **Wear Parts:** * Agricultural tools (plow shares, cultivator teeth), chain links, grader blades, liners. * **Shafts & Pins:** * High-strength axles, rollers, dowel pins, and mandrels requiring wear resistance. * **Cold Headed Fasteners:** * High-grade bolts, screws, and rivets (when sourced as spheroidized annealed wire/bar). --- #### **6. Relevant International & Industry Standards** AISI 1075 is covered under multiple bar and spring steel specifications. | Standard System | Standard Designation | Title / Scope (Relevant to Bar Products) | | :--- | :--- | :--- | | **AISI / SAE / UNS (USA)** | **1075, SAE J403, UNS G10750** | Standard Grade Designation | | **ASTM (USA)** | **ASTM A29/A29M** | Specification for Steel Bars, Carbon and Alloy, Hot-Wrought and Cold-Finished | | **ASTM (USA)** | **ASTM A689** | Specification for Carbon and Alloy Steel Bars for Springs | | **ASTM (USA)** | **ASTM A576** | Specification for Steel Bars, Carbon, Hot-Wrought, Special Quality | | **DIN / EN (Germany/EU)** | **1.1231 / C75W2** | EN 10083-2: Steel for quenching and tempering. Common equivalent. | | **JIS (Japan)** | **SUP3, SUP4** | Spring Steel (JIS G4801). **SWRH77A/B** is a wire rod equivalent. | | **GB (China)** | **75#** | Quality Carbon Structural Steel (GB/T 699). **65Mn** is a common spring steel alternative. | --- ### **Processing Pathway & Selection Guide** 1. **Select Initial Condition:** * **Hot-Rolled:** For general machining/forging where final heat treatment will be applied. * **Cold-Drawn:** For improved dimensional accuracy, surface finish, and increased yield strength. * **Spheroidized Annealed:** For severe cold forming operations (e.g., cold heading, intense bending). 2. **Fabrication:** Machine, forge, or form the component. 3. **Heat Treatment (Critical):** * **Austenitize:** ~790-815°C (1450-1500°F). * **Quench:** Typically in oil (for less severe distortion) or agitated water. * **Temper:** Immediately after quenching. Temperature determines final hardness/strength/toughness balance (e.g., 400°C/750°F for springs, 200°C/400°F for maximum hardness). **Summary:** AISI 1075 Carbon Steel Bar is a versatile, high-performance material whose value is realized through proper thermal processing. It is the industry-standard choice for demanding spring applications and any component where a combination of high strength, resistance to wear, and durability is paramount. When selecting, careful attention must be paid to the supplied condition to match the intended fabrication method. -:- For detailed product information, please contact sales. -: AISI 1075 Carbon Steel Bar Specification Dimensions Size： Diameter 20-1000 mm Length <4868 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 1075 Carbon Steel Bar Properties -:- For detailed product information, please contact sales. -:
