The bottom line: this drawn over mandrel, ASTM A513 tube is for buyers who prioritize strength and dimensional consistency in projects such as shafts, spindles, and custom pins, with the single biggest reason to buy being its robust 1018 carbon steel construction that delivers rigidity and long-term service in mechanical applications.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 1018 carbon steel provides solid tensile strength and rigidity for load-bearing parts and general machinery use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Drawn over mandrel cold roll tubing yields a smoother surface and tighter tolerances for better fit and finish in machined components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e Meets ASTM-A513, offering assurance that the tubing adheres to common dimensional and material expectations for structural tubing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 1-1\/8 in outside diameter with a 0.095 in wall gives a balance of strength and machinability for pins, shafts, and spindles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e Supplied in a 48 in length that is convenient for cutting multiple parts or leaving long stock for machining down to finished sizes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon uses:\u003c\/strong\u003e Typical applications such as sprockets, rods, and fuel tank fittings benefit from the steel's durability and consistent cross section.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe tubing is best for hobby machinists, small fabrication shops, and maintenance teams that need a dependable piece of shaft or rod stock with good strength and consistent OD\/ID for turning and drilling.
