Applications SAE 4340 is widely used in the manufacturing of high-strength components like aircraft landing gear, crankshafts, connecting rods, gears, and other high-stress applications in the aerospace, automotive, and oil & gas industries.
Melting & Refining Method SAE 4340 is generally produced using Electric Arc Furnace (EAF) or Basic Oxygen Furnace (BOF) methods, with secondary refining like Vacuum Degassing (VD) and Ladle Refining Furnace (LRF) for superior quality.
Rolling Route The material is produced via the Continuous Casting route, where molten steel is cast into billets and then hot rolled into desired bar sizes.
Quality Control Strict quality control processes are implemented, including chemical analysis, mechanical testing, and dimensional checks to ensure product quality.
Surface Condition Hot Rolled Bars may have a scale-covered surface, which can be removed through pickling, shot blasting, or machining as per customer requirements.
Traceability Each batch is fully traceable back to its heat number, ensuring documentation of all chemical and mechanical properties.
