ASTM A513-88/ASME SA513 ELECTRIC RESISTANCE WELDED CARBON AND ALLOY STEEL MECHANICALTUBING

SunnySteel Tubing produces round carbon and alloy electric resistance welded (ERW) mechanical tubing to ASTM specifications A513 Type1A (hot rolled), Type 1B (pickled & oiled) and Type 2 (cold rolled). Produced in sizes ranging from 1.05 inch OD up to 12.75 inch OD and in nominal wall thicknesses beginning at 18 gauge (0.049") and heavier, ASTM A513 tubing is used in a variety of industrial, agricultural, and transportation related end uses. For a complete listing of sizes produced, please visit our Steel Tubing Product Catalog.
ASTM A513 Type 1A & 1B
ASTM A513 Type 1A mechanical tubing is produced from hot rolled strip steel while A513 Type 1B tubing is produced from hot rolled strip steel that has been pickled to remove scale then oiled to provide a cleaner surface than hot rolled. A513 Type 1 tubing provides more specific tolerances for OD, wall thickness, length and straightness tolerances than pipe and structural tubing specifications. It is often is used in applications where bending, flanging, flaring or flattening is required. Tubing produced to the A513 specification also provide improved ductility with its closely controlled carbon steel grades.
ASTM A513 Type 2
ASTM A513 Type 2 is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a more narrow range of mechanical properties than A513 Type 1. A513 Type 2 tubing is used in a variety of applications where surface condition is critical and where further polishing or plating of the tubing is required. The maximum wall thickness for cold rolled tubing is 0.120" nominal.
