Maraging 300 Steel Round Bar — Technical and Purchasing Reference
| Item | Guidance |
|---|---|
| Material / product designation | Maraging 300 Steel Round Bar |
| Relevant purchasing specification | Specify Maraging 300 / C300 and applicable AMS grade standard |
| Material / delivery condition | Require solution-treated/aged condition and corresponding mechanical properties |
| Common machining or wear uses | Aerospace structural parts, high-strength shafts, tooling and mechanical components |
| Service/selection consideration | The aging condition and melt route materially affect guaranteed strength; a trade name alone is insufficient. |
| 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
The aging condition and melt route materially affect guaranteed strength; a trade name alone is insufficient. Common uses include aerospace structural parts, high-strength shafts, tooling 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?
Require solution-treated/aged condition and corresponding mechanical properties. 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?
The aging condition and melt route materially affect guaranteed strength; a trade name alone is insufficient. Obtain approval against the drawing and verify the ordered chemistry, mechanical properties, finishing response and documentation.
