Alloy Steel Round Bars
Alloy steel round bars come in various grades like A-182, F5, F9, F11, F12, F22, and F91. These materials are crafted from corrosion-resistant and highly durable metal alloys. Each grade has a unique composition, ensuring they meet specific performance requirements.
The composition of these round bars typically includes carbon, manganese, chromium, molybdenum, phosphorus, and sulfur. They exhibit excellent corrosion resistance and strength, with a minimum tensile strength ranging between 850MPa and 1000MPa. Additionally, they are designed to withstand wear and tear effectively. For instance, the SAE 4140 rod contains carbon, silicon, nickel, phosphorus, manganese, chromium, and sulfur.
