| Typical Mechanical Properties |
|
| Chemical Composition |
|
| Applications | SAE 1018 is commonly used in the manufacturing of shafts, pins, rods, spindles, and machinery parts where better weldability, machinability, and surface finish are required. |
| Melting & Refining Method | SAE 1018 is typically produced using Electric Arc Furnace (EAF) or Basic Oxygen Furnace (BOF) methods, followed by secondary refining techniques like Ladle Refining Furnace (LRF) to ensure consistent chemical composition and reduced impurities. |
| Rolling Route | The material is produced through the Continuous Casting route, where the molten steel is cast into billets, followed by hot rolling into the desired round bar sizes. |
| Quality Control | Rigorous quality control measures are implemented throughout the manufacturing process, including chemical analysis, mechanical testing, dimensional checks, and surface inspection to ensure the highest standards of product quality. |
| Surface Condition | Hot Rolled Bars may have a scale-covered surface, which can be removed by pickling, shot blasting, or machining as per customer requirements. |
| Traceability | Each batch is fully traceable back to its heat number, ensuring that all chemical and mechanical properties are well-documented and can be verified. |
