DOM Steel Tubing: Drawn-over-mandrel (DOM) tubing is a manufacturing product form, not a single alloy grade. Tube OD, wall thickness, dimensional tolerance, and steel chemistry must all be specified.

DOM Steel Tubing — Technical and Purchasing Reference
| Item | Guidance |
|---|---|
| Material / product designation | DOM Steel Tubing |
| Relevant purchasing specification | ASTM A513 Type 5 for appropriate DOM mechanical tubing |
| Material / delivery condition | State tube steel grade, drawing condition, OD, ID/wall, straightness and finish |
| Common machining or wear uses | Hydraulic tubes, precision sleeves, automotive and mechanical components |
| Service/selection consideration | Do not assume a DOM tube has the same mechanical properties as hot-finished pipe or seamless tubing. |
| Mozaic bar-processing scope | Custom OD grinding, polishing, straightening, cutting and packaging by inquiry |
Reference information only, not a certified melt analysis, mechanical test report or inventory guarantee. Use the current governing material/product specification and lot-specific mill documentation to qualify any order.
Application Selection and Material Limitations
Do not assume a DOM tube has the same mechanical properties as hot-finished pipe or seamless tubing. Common uses include hydraulic tubes, precision sleeves, automotive and mechanical components. Suitability depends on grade chemistry, dimensions, strength and condition, the working environment and any surface or dimensional specifications. A related material should not be substituted solely because its marketing name sounds similar.
Centerless Grinding and Bar Finishing
Mozaic Precision Metals can review sourcing and centerless grinding, bar straightening, polishing, chamfering, cut-to-length and packaging for this product. Specify starting size, finished OD and diameter tolerance, length, surface roughness, straightness and inspection requirements separately. Actual capability depends on the material condition and geometry.

Frequently Asked Questions
Which material condition should I order?
State tube steel grade, drawing condition, OD, ID/wall, straightness and finish. Include the applicable purchasing standard, section size, certifications and target properties; heat-treatment schedules and mechanical values cannot be assumed across all conditions.
Can I substitute a similar grade?
Do not assume a DOM tube has the same mechanical properties as hot-finished pipe or seamless tubing. Obtain approval against the drawing and verify the ordered chemistry, mechanical properties, finishing response and documentation.
