It is renowned for its excellent balance of strength, toughness, hardenability, and fatigue resistance. The addition of chromium and molybdenum enhances its depth-hardening characteristics, making it particularly suitable for components requiring high core strength and good wear resistance in demanding applications. It is widely used in the automotive, aerospace, and general engineering industries for critical, heavily stressed parts. **Key International Standards & Designations** * **UNS:** G40530 * **AISI/ASTM:** 4053 * **SAE:** 4053 * **Germany (DIN):** Approx. 1.7033 / 34CrMo4 * **Europe (EN):** 1.7220 / 34CrMo4 * **Japan (JIS):** SCM430 * **Note:** While closely related, specifications across standards may have slight variations in composition or热处理 requirements. UNS G40530 and AISI 4053 are the primary references for this product. **Chemical Composition (Typical, Weight %)** The composition is carefully controlled to achieve the desired mechanical properties. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 0.30 - 0.37 | **Molybdenum (Mo)** | 0.15 - 0.25 | | **Manganese (Mn)** | 0.60 - 0.90 | **Phosphorus (P)** | ≤ 0.035 | | **Silicon (Si)** | 0.15 - 0.35 | **Sulfur (S)** | ≤ 0.040 | | **Chromium (Cr)** | 0.80 - 1.10 | **Iron (Fe)** | Balance | *This is a typical range. Specific limits may vary per customer specification or standard revision.* **Physical & Mechanical Properties** Properties are highly dependent on the heat treatment condition (e.g., annealed, normalized and tempered, quenched and tempered). * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Melting Point:** Approx. 1420 - 1460 °C (2590 - 2660 °F) * **Modulus of Elasticity:** 205 GPa (29.7 x 10⁶ psi) * **Thermal Conductivity:** ~42.6 W/m·K (at 100°C) * **Typical Mechanical Properties (Quenched & Tempered):** * **Tensile Strength:** 850 - 1000 MPa (123 - 145 ksi) * **Yield Strength (0.2% Offset):** 650 MPa min (94 ksi min) * **Elongation (in 50mm):** 15% min * **Reduction of Area:** 50% min * **Hardness:** 248 - 302 HB (Approx. 25 - 32 HRC, varies with tempering temperature) * **Hardenability:** Good to excellent, with molybdenum minimizing susceptibility to temper embrittlement. **Product Forms & Applications** AISI 4053 is typically supplied in the annealed or normalized condition for machining, followed by final heat treatment by the customer. * **Available Forms:** * Round Bars (Hot-rolled, forged, cold-finished) * Flat Bars * Forging Blanks / Billets * Sheets & Plates (less common) * **Primary Applications:** * **Automotive:** High-stress components such as **crankshafts**, **axle shafts**, **connecting rods**, **gears**, **pinions**, and steering parts. * **Aerospace:** **Landing gear components**, engine mounts, and other structural parts requiring high strength-to-weight ratio. * **Oil & Gas:** **Drill collars**, tool joints, and valve components. * **General Engineering:** **High-strength bolts and fasteners**, spindles, studs, heavy-duty shafts, and machinery parts subjected to high动态载荷 and fatigue. **Heat Treatment** * **Annealing:** Heated to 845-900°C (1550-1650°F) and slowly cooled to improve machinability. * **Normalizing:** Heated to 870-925°C (1600-1700°F) and air-cooled to refine grain structure. * **Quenching & Tempering (Typical):** * **Austenitizing:** 830-860°C (1525-1580°F), oil quench. * **Tempering:** 540-660°C (1000-1220°F), depending on the required strength/hardness level. **Note:** Temper above 400°C (750°F) and cool rapidly to avoid temper embrittlement. **Why Choose AISI 4053?** * **Proven Reliability:** A well-established grade with predictable performance. * **Excellent Hardenability:** Allows for uniform strength in thicker sections. * **Good Fatigue Strength:** Ideal for cyclic loading applications. * **Favorable Strength/Toughness Balance:** Provides durability under impact or shock loads. * **Good Machinability (in annealed condition):** Facilitates the manufacturing of complex parts.
