Built to meet ASTM A513, this 2in outside diameter, 1in inside diameter tube with a 0.50in wall and 24in length is aimed at users who need rigid, predictable tubing for mechanical applications. The tubing's drawn over mandrel construction and cold rolling give it a smoother bore and higher yield strength than hot rolled alternatives, making it the go-to option for applications where durability matters.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eASTM A513 compliance:\u003c\/strong\u003e Provides confidence in material quality and manufacturing consistency for industrial or automotive projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrawn over mandrel:\u003c\/strong\u003e Ensures a smoother internal bore and more consistent wall thickness than non-drawn welded tubing, improving fit and flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCold rolled finish:\u003c\/strong\u003e Delivers greater yield strength and hardness compared with hot rolled tubing, which helps resist deformation under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThick 0.50in wall:\u003c\/strong\u003e Offers exceptional rigidity and strength for shafts, pins, or structural supports where high section modulus is needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensional sizes 2in x 1in:\u003c\/strong\u003e Matches fractional tubing needs for fittings and assemblies commonly used in HVAC and automotive lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1018 carbon steel characteristics:\u003c\/strong\u003e Makes the tube well suited to pins, rods, spindles and sprockets where machinability and strength are balanced.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis tubing is intended for fabricators, mechanics, and HVAC technicians who need a high-strength, consistent-dimension tube for fluid transfer lines, structural supports, or mechanical components.
