ASTM A513 Type 5 Drawn-Over-Mandrel (DOM) Carbon Steel Mechanical Tubing 1. Material Overview ASTM A513 Type 5 designates electric-resistance-welded (ERW) carbon steel tubing that undergoes a Drawn-Over-Mandrel (DOM) process. This cold-drawing ensures close control of dimensions—tight outside/inside diameter and wall thickness tolerances—uniform concentricity, dense surfaces, and predictable mechanical strength. It’s widely used for precision mechanical parts including

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.

Round DOM Roll Cage Tubing Structural Steel Pipe DOM Tubing For Roll Cage 【Material】 Drawn Over Mandrel (DOM) tubing is produced by electric resistance welding of carbon-steel strip followed by cold drawing over a mandrel to remove weld flash and enhance mechanical properties. This process yields: Uniform wall thickness and concentric OD/ID. Improved yield and tensile strength compared to standard ERW tubes. Smooth OD/ID surfaces, requiring minimal machining. 【Specifications】

Dom Steel Tubing 1026 Drawn Over Mandrel Steel Tube For Precision Machinery Material AISI 1026 is a medium-carbon steel known for its balanced combination of strength, ductility, and machinability. Produced via cold drawn over mandrel (DOM) processing, it achieves a refined surface finish and tight dimensional tolerances suitable for high-precision applications. Specifications Grade: AISI/SAE 1026 (UNS G10260) Process: Cold Drawn Over Mandrel (DOM) Shape: Round tube Outside

T5 DOM Steel Tube Drawn Over Mandrel Low Carbon Steel Welded Pipe For Mechanical This product is a Drawn-Over-Mandrel (DOM) steel tube manufactured from low-carbon welded pipe, designed for demanding mechanical applications requiring high precision, uniform mechanical properties, and excellent surface finish. It is cold-drawn over a mandrel to achieve tight tolerances on outside diameter (OD), inside diameter (ID), and wall thickness, resulting in smooth, oxide-free surfaces
