The single biggest reason to buy is its material grade and dimensional combination: drawn over mandrel A513 1018 carbon steel that meets ASTM-A513 offers reliable mechanical properties for pins, rods, shafts and spindles where rigidity matters. Buyers should expect good value and solid steel quality rather than exceptional ease of welding or extreme machinability.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e The A513 1018 carbon steel construction provides high strength and rigidity for load-bearing parts and repairs.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecision tube:\u003c\/strong\u003e Drawn over mandrel manufacturing yields a straight, consistent tube profile useful for shafts and spool-type components.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 1-1\/4 in outside diameter with a 0.87 in inside diameter and 0.188 in wall gives a stout cross section suitable for pins and axles.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e The 36 in length is long enough for multiple small jobs or for cutting to custom lengths without loss of material integrity.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e Conformance to ASTM-A513 ensures the tubing meets common industrial expectations for mechanical performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis tubing is aimed at metalworkers who need strong, straight carbon steel tubing for mechanical parts: machinists making shafts, hobbyists repairing fuel tank linkages or drivetrain components, and fabricators building fixtures or supports. Its stiffness and the 1018 grade make it a good choice where strength and dimensional stability are priorities.\u003c\/p\u003e\n\n\u003cp\u003eThose who need excellent weldability or maximum ease of machining should take caution; A513 1018 has slightly lower machinability and weldability compared with some lower-carbon or engineered weldable steels. Also, if you require unusually tight internal bored tolerances, confirm the ID fits your needs because a few users noted the inner diameter can be slightly smaller than expected.\u003c\/p\u003e\n\n\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eHigh strength and rigidity make it dependable for shafts, pins, and sprocket supports.\u003c\/li\u003e\n \u003cli\u003eDrawn over mandrel finish produces a straight, consistent tube for predictable installation.\u003c\/li\u003e\n \u003cli\u003eGood value for solid steel stock that meets ASTM-A513 standards.\u003c\/li\u003e\n \u003cli\u003e36 in length provides flexibility for multiple cuts or larger projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eLower machinability and weldability than some other steels, so expect slower cutting and more attention when welding.\u003c\/li\u003e\n \u003cli\u003eOccasional reports of a slightly smaller inner diameter, so measure before assuming a slip fit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n \u003ctr\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003ctd\u003eASTM-A513\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e1018 Carbon Steel (A513)\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eOutside Diameter\u003c\/td\u003e\n\u003ctd\u003e1-1\/4 in\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eInside Diameter\u003c\/td\u003e\n\u003ctd\u003e0.87 in\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eWall Thickness\u003c\/td\u003e\n\u003ctd\u003e0.188 in\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e36 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eOur Verdict\u003c\/h2\u003e\n\u003cp\u003eThe A513 cold roll round tubing is a practical choice for anyone needing strong, straight shaft stock and reliable mechanical performance at a reasonable price.
