ASTM A513 Type 5 DOM Round Steel Tube Cold-Worked Carbon Steel

ASTM A513 Type 5 DOM Round Steel Tube — Cold-Worked Carbon Steel Welded Mechanical Tubing

Material
Drawn Over Mandrel (DOM) round mechanical tubing manufactured to ASTM A513 Type 5. It begins as ERW tubing and is then cold-drawn through a mandrel and die to refine the grain, improve surface finish, increase strength, and deliver very tight OD/ID concentricity and wall tolerances. Typical melt chemistries used are SAE/AISI 1020 and 1026 low-carbon steels.

Specifications

  • Manufacturing route: ERW → DOM cold drawing; available “as drawn (+C)” or stress-relieved/annealed (SRA).

  • Common grades: 1020 / 1026.

  • Size range (typical): OD 9.52–203.2 mm (⅜–8″); many suppliers list up to 12″ OD and heavy walls.

  • Straightness (typical): 0.030 in per 3 ft (0.76 mm/m) ≤ 8.00″ OD; 0.060 in per 3 ft for ≥ 8.00″ OD.

  • Wall tolerance: tight plus/minus controls per A513 tables (±0.002–0.004 in typical, depending on OD/wall).

  • Surface & geometry: smooth OD/ID, excellent concentricity, uniform wall.

SAE/AISI 1020 (reference) Cold-drawn / annealed ≈420 ≈350 ≈15 Reference properties for 1020 low-carbon steel.

Key Characteristics

  • Tight OD/ID concentricity and uniform wall for precision fit-ups and machining.

  • Higher strength than as-welded ERW due to cold work; consistent hardness and microstructure.

  • Excellent machinability and weldability (low-carbon 1020/1026 chemistries).

  • Clean, smooth surfaces; straightness suitable for high-speed assembly.

Applicable Standards

  • ASTM: ASTM A513 Type 5 — ERW DOM mechanical tubing.

  • EN: EN 10305-2 — Welded cold-drawn precision steel tubes (grades E235/E355).

  • JIS: JIS G3445 — Carbon steel tubes for machine structural purposes (e.g., STKM13C).

  • GB (China): GB/T 31315-2014 — Cold-drawn/cold-rolled precision welded steel tubes for mechanical structures.

  • GOST (Russia): GOST 10704 / 10705 — Electrically welded longitudinal steel pipes (general/structural use).

Applications

  • Automotive: suspension links, steering columns, driveshaft components, roll-cage members.

  • Hydraulics & pneumatics: cylinder barrels, shock/strut bodies (after honing, where specified).

  • General machinery & fabrication: jigs/fixtures, conveyors, frames, agricultural implements, furniture tubing.
