DOM Carbon Steel Tube for Precision Machinery 30-425mm OD

Dom Round Tubing Welded Carbon Round Steel Tube for Precision Machinery

Material Overview

Dom Round Tubing—commonly referred to as DOM (Drawn Over Mandrel)—is produced from electric-resistance-welded (ERW) steel (typically AISI 1020, 1026, or equivalent). It undergoes cold drawing over a mandrel to remove weld flash, enhancing dimensional accuracy, concentricity, strength, and surface quality. It is widely used in precision machinery due to these enhanced characteristics.

Specifications

  • Standards: Conforms to ASTM A513 Type 5 (mechanical tubing), as well as international equivalents like EN DIN EN 10250‑2 (C22E), GOST 10704‑91, JIS G3445 STKM 13B, and GB/T 31315‑2014.

  • Typical Grades: AISI 1020 is most common; 1026 is used for larger ODs or thicker walls. Some sources also list ST52.3.

  • Size Range: OD from ~0.188″ to 12″ (4.8 mm–127 mm); wall thickness from 0.028″ to 0.625″ (0.7 mm–15.9 mm).

Chemical Composition Comparison

Here's a table comparing chemical composition among five common low‑carbon steel grades used in DOM/precision tubing:

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


Mechanical Properties Comparison

Mechanical properties for the same five grades are outlined 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

  • Tight Dimensional Tolerances: Cold drawing yields excellent OD/ID accuracy and concentricity

  • Surface Finish: Smooth, flash-free internal and external surfaces

  • Enhanced Mechanical Performance: Improved tensile/yield strength from cold worked processing; still offers great machinability and weldability, especially in 1020

  • Cost-Efficient: Offers high performance at lower cost relative to seamless options

International Standard Equivalents

  • EN: DIN EN 10250‑2 (C22E)

  • GOST: GOST 10704‑91

  • JIS: JIS G3445 STKM 13B

  • GB: GB/T 31315‑2014 (cold‑drawn/rolled precision welded tubes)

Application Fields

DOM tubing is favored in precision-sensitive mechanical applications. Typical usage includes:

  • Hydraulic Systems: Cylinder barrels, piston rods

  • Automotive: Axles, gears, bushings, steering components

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

  • Agricultural Equipment: Drive shafts, rollers, frame members

  • Consumer & Construction: Furniture frames, accurate support members
