AISI 6150H Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper Product Information -:- For detailed product information, please contact sales. -: **Product Introduction: AISI 6150H Steel, Oil Quenched & Tempered (845°C / 540°C)** AISI 6150H is a premium chromium-vanadium alloy steel specifically engineered for high hardenability ("H" designation). When subjected to the precise heat treatment of oil quenching from 845°C (1550°F) followed by tempering at 540°C (1000°F), it achieves an exceptional combination of high strength, excellent toughness, and superior fatigue resistance. This condition represents the final, ready-for-service state of the material, optimized for the most demanding dynamic and high-stress applications. **1. Chemical Composition (Typical Weight %, AISI Standard)** The composition is tailored to ensure consistent response to the specified heat treatment. * **Carbon (C):** 0.48 - 0.53 * **Manganese (Mn):** 0.70 - 0.90 * **Phosphorus (P):** ≤ 0.035 * **Sulfur (S):** ≤ 0.040 * **Silicon (Si):** 0.15 - 0.30 * **Chromium (Cr):** 0.80 - 1.10 * **Vanadium (V):** 0.15 min * *Note:* The H-grade ensures hardenability, guaranteeing uniform properties across different sections even with minor compositional variations. **2. Physical & Mechanical Properties (Oil Quenched & Tempered @ 540°C)** This heat treatment produces a tempered martensitic microstructure, balancing strength and ductility. * **Typical Hardness:** Rockwell C 38 - 45 HRC (Approx. Brinell 352 - 429 HBW) * **Tensile Strength:** ~ 1240 - 1520 MPa (180 - 220 ksi) * **Yield Strength (0.2% Offset):** ~ 1100 - 1380 MPa (160 - 200 ksi) * **Elongation (in 50 mm):** ~ 12 - 16% * **Reduction of Area:** ~ 45 - 55% * **Impact Toughness (Charpy V-Notch):** Typically 27 - 41 J (20 - 30 ft-lb) at room temperature * **Density:** 7.85 g/cm³ * **Modulus of Elasticity:** 200 GPa (29,000 ksi) **3. Key Features & Performance Characteristics** * **High Strength-to-Toughness Ratio:** The 540°C (1000°F) tempering temperature provides an optimal balance, offering very high yield strength while retaining significant ductility and impact resistance. * **Superior Fatigue and Endurance Limit:** The combination of high strength, fine microstructure, and the strengthening effect of vanadium carbides makes it exceptionally resistant to failure under cyclic loading. * **Excellent Hardenability:** The "H" grade ensures full through-hardening in moderate to large sections with oil quenching, resulting in uniform core properties. * **Good Wear Resistance:** The high hardness and strong martensitic matrix provide good resistance to abrasion and galling. * **Dimensional Stability:** The tempering at 540°C effectively relieves quenching stresses, promoting stability in precision components. **4. Primary Applications** This heat-treated condition is specified for critical, safety-related components subjected to high dynamic stresses. * **Automotive & Racing:** High-performance gear shafts, torsion bars, heavy-duty axle shafts, piston pins, valve springs (for lower stress ranges), and high-stress suspension components. * **Aerospace:** Aircraft landing gear components, engine mounts, critical bolts, and flight control actuators. * **Industrial Machinery:** Heavy-duty gears, power transmission shafts, high-strength connecting rods, hydraulic cylinder rods for high-pressure systems, and drill collars. * **Oil & Gas:** Critical valve components, tool joints, and downhole tooling requiring high strength and fatigue resistance. * **Tooling:** High-strength jigs, fixtures, and die components. **5. Relevant International Standards & Specifications** The final heat-treated condition is often called out on engineering drawings, referencing both material and treatment. * **USA:** ASTM A322 (Standard Specification for Steel Bars, Alloy, Standard Grades), SAE J404 (Chemical Compositions) & J1868 (Hardenability). Often specified as "6150H, Q&T to HRC 40-44". * **AMS (Aerospace Material Specification):** AMS 6440H (Steel Bars, 1.0Cr-0.2V (0.48-0.53C) (6150H) Consumable Electrode Melted, Normalized and Tempered). * **Germany:** DIN EN 10083-3 (50CrV4, quenched and tempered). Tempering conditions are specified separately. * **International:** ISO 683-18:1996. The tempering condition is part of the delivery requirement. * **UNS Designation:** G61500H **Conclusion** AISI 6150H steel, oil quenched and tempered at 540°C, represents a high-performance engineering material at its peak condition. It delivers an outstanding synergy of very high strength, good toughness, and exceptional fatigue life, making it a material of choice for mission-critical components across advanced automotive, aerospace, and heavy machinery sectors. The guaranteed hardenability ensures reliability and consistency in final parts, providing engineers with a predictable and robust solution for extreme operating conditions. -:- For detailed product information, please contact sales. -: AISI 6150H Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper Specification Dimensions Size： Diameter 20-1000 mm Length <6310 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 6150H Steel, oil quenched 845°C (1550°F), 540°C (1000°F) temper Properties -:- For detailed product information, please contact sales. -:
