AISI 6150H Steel, normalized Product Information -:- For detailed product information, please contact sales. -: **Product Introduction: AISI 6150H Steel, Normalized Condition** AISI 6150H is a versatile chromium-vanadium alloy steel supplied to specific hardenability ("H") band requirements. When provided in the normalized condition, this steel offers an advantageous combination of enhanced mechanical properties and good machinability compared to the annealed state. The normalization heat treatment refines the grain structure, improves uniformity, and produces a higher, more consistent strength level, making it an ideal starting condition for components requiring further heat treatment or for applications demanding moderate strength. **1. Chemical Composition (Typical Weight %, AISI Standard)** The composition is controlled primarily to meet hardenability limits. * **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 allows controlled compositional variations to guarantee hardenability bands. **2. Physical & Mechanical Properties (Normalized Condition)** Normalization involves austenitizing followed by air cooling, resulting in a finer pearlitic-ferritic microstructure. * **Typical Hardness:** Brinell 207-241 HBW * **Tensile Strength:** ~ 690-860 MPa (100-125 ksi) * **Yield Strength:** ~ 485-620 MPa (70-90 ksi) * **Elongation:** ~ 18-22% * **Machinability:** Fair to Good (generally better than the quenched & tempered condition, but slightly less than the annealed condition). * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 190-210 GPa (27,500-30,500 ksi) **3. Key Features & Subsequent Processing** * **Refined Grain Structure:** Normalization eliminates coarse grains from prior hot working, leading to more uniform properties and improved toughness. * **Enhanced Strength:** Provides a stronger baseline than annealed material, which can be beneficial for handling, intermediate fabrication, or for final applications not requiring full hardening. * **Ideal Pre-Condition:** The uniform, fine-grained normalized structure is excellent for subsequent machining and provides a consistent, predictable starting point for final heat treatment (quenching & tempering), minimizing distortion risks. * **Hardenability:** The guaranteed "H" band ensures deep and uniform hardening potential during final quenching. **4. Primary Applications** Normalized AISI 6150H is used where a balance of strength, machinability, and predictable response to final heat treatment is critical. * **Forged & Machined Components:** Commonly used as the starting material for forged parts like crankshafts, connecting rods, gear blanks, and axle shafts that will be machined and then through-hardened. * **Heavy-Duty Shafting:** For applications requiring moderate as-supplied strength for handling and fabrication before final hardening. * **Industrial Machinery:** Components such as spindles, pins, and bolts that benefit from a normalized structure for consistent final properties. * **Gears and Sprockets:** As a pre-hardened stock material before gear cutting and final heat treatment. **5. Relevant International Standards** The normalized condition is typically specified as a supplementary requirement to the base material standard. * **USA:** ASTM A29/A29M (Standard Specification for Steel Bars, Carbon and Alloy, Hot-Wrought and Cold-Finished - Normalized condition can be specified), SAE J1868. * **Germany:** DIN EN 10083-3 (Steel for quenching and tempering - Part 3: Technical delivery conditions for alloy steels). The normalized condition is often specified. * **International:** ISO 683-18:1996 (Can include normalization requirements). * **Japan:** JIS G4052 (SCr440H). Normalizing is a common supplementary treatment. * **UNS Designation:** G61500H **Conclusion** AISI 6150H steel in the normalized condition offers a superior balance of strength, microstructural uniformity, and machinability. It serves as an optimal interim or pre-hardened state for demanding components that will undergo final heat treatment, ensuring consistent performance, reduced distortion, and reliable service in high-stress automotive, industrial, and machinery applications. The guaranteed hardenability remains its defining feature, providing engineers with predictable transformation characteristics during final quenching. -:- For detailed product information, please contact sales. -: AISI 6150H Steel, normalized Specification Dimensions Size： Diameter 20-1000 mm Length <6309 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, normalized Properties -:- For detailed product information, please contact sales. -:
