AISI 6150 Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper Product Information -:- For detailed product information, please contact sales. -: ### **Product Introduction: AISI 6150 Alloy Steel – Oil Quenched & Tempered** **Product Designation:** AISI 6150 Steel, Oil Quenched at 845°C (1550°F) and Tempered at 540°C (1000°F) **Overview:** AISI 6150 is a versatile chromium-vanadium alloy steel renowned for its excellent combination of high strength, good toughness, and superior fatigue resistance. The specific heat treatment of oil quenching from 845°C followed by tempering at 540°C produces a tempered martensitic microstructure. This treatment optimally balances the material's properties, resulting in a high-strength condition with considerable ductility and impact resistance, making it ideal for demanding high-stress applications. --- ### **1. Chemical Composition (Nominal, wt. %)** The composition is formulated to provide hardenability, strength, and wear resistance. | Element | Carbon (C) | Manganese (Mn) | Silicon (Si) | Chromium (Cr) | Vanadium (V) | Iron (Fe) | | :--- | :---: | :---: | :---: | :---: | :---: | :---: | | **Content** | 0.48 - 0.53 | 0.70 - 0.90 | 0.15 - 0.30 | 0.80 - 1.10 | 0.15 min | Balance | *Note: Phosphorus (P) and Sulfur (S) are maintained at low levels (typically ≤ 0.035% each) to ensure purity and good toughness.* --- ### **2. Physical & Mechanical Properties (Typical after 845°C OQ & 540°C Temper)** *Properties are indicative and can vary with exact section size and process parameters.* * **Tensile Strength:** 1,240 – 1,380 MPa (180 – 200 ksi) * **Yield Strength (0.2% Offset):** 1,100 – 1,240 MPa (160 – 180 ksi) * **Elongation (in 50 mm / 2”):** 12 – 16% * **Reduction of Area:** 45 – 55% * **Hardness:** 38 – 44 HRC * **Impact Toughness (Charpy V-notch):** 40 – 55 J (30 – 40 ft·lb) at room temperature * **Modulus of Elasticity:** ~205 GPa (29,700 ksi) * **Density:** 7.85 g/cm³ (0.284 lb/in³) --- ### **3. Key Characteristics & Advantages** * **High Strength-to-Weight Ratio:** Offers significant strength while remaining lighter than many high-alloy alternatives. * **Excellent Fatigue Strength:** The chromium and vanadium content, combined with the tempered martensite structure, provides exceptional resistance to cyclic loading, crucial for springs and rotating parts. * **Good Wear Resistance:** Suitable for components subject to sliding contact and abrasion. * **Favorable Hardenability:** The alloying elements, particularly chromium, ensure good depth of hardening in moderate sections during oil quenching. * **Machinability & Grindability:** In the annealed condition prior to heat treatment, it offers fair machinability. In the final heat-treated condition, it can be machined or ground with appropriate techniques. --- ### **4. Typical Product Applications** This specific heat-treated condition of AISI 6150 is extensively used in high-performance mechanical components requiring durability under stress: * **Heavy-Duty Springs:** Coil springs, leaf springs (especially for automotive and rail applications), and torsion bars. * **Power Transmission Components:** Gears, shafts, spindles, and couplings. * **Tooling & Machinery Parts:** Drill collars, mandrels, bolts, and high-strength fasteners. * **Agricultural & Off-Highway Equipment:** Critical pins, axles, and linkages. * **Aerospace Components:** Non-critical structural parts, landing gear components (secondary). --- ### **5. Relevant International & Equivalent Standards** AISI 6150 is recognized under various international standards with closely similar compositions. | Standard Designation | Country/Region | Comparable Grade | Condition Specified | | :--- | :--- | :--- | :--- | | **AISI 6150** | USA | - | Oil Quenched & Tempered | | **ASTM A322** | USA | Grade 6150 | Standard for alloy steel bars, subject to heat treatment | | **SAE J404** | USA | SAE 6150 | Chemical composition standard | | **UNI** | Italy | **51CrV4** | A very common European equivalent, nearly identical | | **DIN / EN** | Germany / EU | **1.8159** (50CrV4) | Slight compositional variations, functionally equivalent | | **BS** | United Kingdom | **735A50** | | | **JIS** | Japan | **SCr440V** | Similar, with minor compositional differences | | **GOST** | Russia | **50KhFA** | Close equivalent | **Note:** While the chemical compositions are very similar across these standards, specific permissible ranges and mandatory trace elements may differ. The designation **51CrV4 (UNI)** is often considered the direct European counterpart. Material selection should always reference the exact specification required by the application's governing standard. -:- For detailed product information, please contact sales. -: AISI 6150 Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper Specification Dimensions Size： Diameter 20-1000 mm Length <6305 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 6150 Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper Properties -:- For detailed product information, please contact sales. -:
