Supreme Steel Industries

SAE 4340 round bars are high-strength, low-alloy nickel-chromium-molybdenum steels known for superior toughness, fatigue resistance, and durability, often used in critical, high-stress applications. They are heat-treatable and ideal for heavy-duty components like crankshafts, gears, shafts, and landing gear. Key Characteristics and Features

• Composition: Contains, chromium, nickel, and molybdenum for high hardenability and toughness.
• Performance: Excellent fatigue resistance and high strength, typically with tensile strength ranging from 930–1080 MPa and high impact value.
• Heat Treatment: Achieves high strengths through heat treatment (often normalized or quenched and tempered).
• Versatility: Available in hot-rolled, forged, and bright bar forms with good machinability, particularly in the annealed condition.
