DOM Round Steel Tube 1020 Low Carbon Welded Pipe for Mechanical Use

DOM Round Steel Tube 1020 Low Carbon Steel Welded Pipe For Mechanical Equipment

Material

Drawn Over Mandrel (DOM) round steel tubing is produced from an electric-resistance-welded (ERW) tube that is cold drawn through dies and over a mandrel to remove weld flash, achieving precise outside and inside diameters, superior surface finish, and enhanced mechanical properties. This product is manufactured from low-carbon AISI 1020 steel, noted for its excellent weldability, formability, and machinability.

Specifications

  • ASTM Compliance: ASTM A513 Type 5 (DOM mechanical tubing)

  • Outer Diameter: 0.1875" – 5" (4.8 – 127 mm)

  • Wall Thickness: 0.028" – 0.625" (0.7 – 15.9 mm)

  • Tolerances (OD): per ASTM A513 Type 5 (e.g., +0.005"/0.000 for 0.500"–1.699" OD)

  • Length: Standard 6 m (20 ft); custom lengths available on request

Chemical Composition

The table below compares key alloying limits for five common low-carbon steel grades used in DOM and precision tubing:

Grade C (%) Mn (%) P (max %) S (max %)
AISI 1008 (G10080) 0.08 – 0.10 0.30 – 0.50 0.040 0.050
AISI 1010 (G10100) 0.080 – 0.13 0.30 – 0.60 0.040 0.050
AISI 1015 (G10150) 0.13 – 0.18 0.30 – 0.60 0.040 0.050
AISI 1018 (G10180) 0.15 – 0.20 0.60 – 0.90 0.040 0.050
AISI 1020 (G10200) 0.18 – 0.23 0.30 – 0.60 0.040 0.050

Mechanical Properties

Mechanical properties of cold-drawn tubing for these grades are shown below:

Grade Tensile Strength (MPa) Yield Strength (MPa) Elongation (%) Hardness (HB)
AISI 1008 340 285 20 95
AISI 1010 365 305 20 105
AISI 1015 385 325 18 111
AISI 1018 440 370 15 126
AISI 1020 420 350 15 121

Key Features

  • Precise Dimensional Control: Achieves close OD/ID tolerances via cold drawing over mandrel.

  • Superior Surface Finish: Weld flash removed; smooth inner and outer surfaces.

  • Enhanced Strength: Cold work increases yield and tensile strengths over standard ERW tubing.

  • Excellent Machinability: Low-carbon AISI 1020 base offers good machining and weldability.

  • Cost-Effective: Manufactured from widely available low-carbon alloy with efficient ERW and cold-drawn processes.

Execution Standards

  • ASTM A513 Type 5: Electric-resistance-welded, cold-drawn mechanical tubing

  • EN: DIN EN 10250-2 C22E (1.1151) cold-drawn carbon steel round tubes

  • GOST: GOST 10704-91 electric-resistance-welded steel tubes

  • JIS: JIS G3445 STKM 13B carbon steel mechanical structural tubes

  • GB: GB/T 31315-2014 cold drawn or cold rolled precision weld steel tubes for mechanical structures

Application Fields

Mechanical Equipment—widely used where high strength, accuracy, and surface finish are critical:

  • Hydraulic Systems: Cylinder barrels, piston rods

  • Automotive Industry: Axles, gears, bushings, steering components

  • Industrial Machinery: Shafts, spindles, couplings, structural supports

  • Agricultural Machinery: Drive shafts, rollers, frame elements

  • Furniture & Construction: Support tubes, frame members requiring precise fit
