The reviewer found the tubing offers strong material properties and consistent outer dimensions, making it a reliable choice when strength and rigidity matter. Our review highlights that while weldability and machining are slightly reduced compared with softer steels, the overall value, steel quality, and fit were positive in real-world use.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e A513 1018 carbon steel provides high strength and rigidity useful for load-bearing parts and mechanical components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter diameter:\u003c\/strong\u003e The 1.375 in outside diameter gives a predictable external size for press fits and fixture alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner diameter and wall:\u003c\/strong\u003e With a 1.063 in inner diameter and 0.156 in wall thickness, the tube balances stiffness and weight for shafts and spindles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e The 72 in length reduces joints and seams in longer assemblies, simplifying construction and alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification:\u003c\/strong\u003e Meets ASTM A513 standard, which ensures consistent manufacturing and predictable mechanical behavior.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon uses:\u003c\/strong\u003e Typical applications include pins, rods, shafts, spindles, and sprockets where solid mechanical performance is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis tubing is best for machinists, metal fabricators, and DIY mechanics who need a strong, sturdy tube for rotating parts, structural components, or repairs.
