5454 is a magnesium bearing, non heat treatable alloy with excellent corrosion resistance in marine and chemical environments and good behaviour in welded fabrication. Its magnesium content is controlled to avoid sensitization in sustained elevated temperature service, which distinguishes it from 5083 and 5456.
It is a standard material for tanker bodies, pressure vessels and welded structures that run warm.
Stocked as plate, sheet and extrusions in O, H32 and H34 tempers.

Nominal chemistry
Percent by weight, nominal composition per the governing specification. The mill test report for your heat is the controlling document.
Typical mechanical properties
| Condition | Tensile strength | Yield strength | Elongation | Hardness |
|---|---|---|---|---|
| O | ~36 ksi | ~17 ksi | ~22% | - |
| H32 | ~40 ksi | ~30 ksi | ~10% | - |
Typical published values for reference only, not for design. Properties vary with section size, product form and processing. Order to the specification and condition your drawing requires.
Typical applications
- Tank trailers and pressure vessels
- Welded marine structure
- Chemical process equipment
- Elevated temperature welded assemblies
Fabrication notes
Machining
Machines rapidly with sharp, polished, high rake tooling and high surface speeds. Heat treatable alloys cut cleanest in the T temper. Thick plate benefits from stress relieved tempers to limit movement when large volumes of material are removed.
Welding
Weldability varies by series. The 5xxx and 6xxx alloys weld readily with 4043 or 5356 filler; the 2xxx and 7xxx aerospace alloys are normally joined mechanically or by friction stir and specialized processes rather than fusion welding.
Forming
Form in the annealed or freshly solution treated condition where the temper allows, then age to final strength. Bend radii should follow the temper and thickness in the governing specification.
5454 compared with similar grades
5456
Higher magnesium and strength, restricted from sustained service above about 150F.
5052
Lower strength, extremely formable sheet alloy.

5454 frequently asked questions
What is 5454?
5454 is a magnesium bearing, non heat treatable alloy with excellent corrosion resistance in marine and chemical environments and good behaviour in welded fabrication. Its magnesium content is controlled to avoid sensitization in sustained elevated temperature service, which distinguishes it from 5083 and 5456.
What forms is 5454 available in?
We supply 5454 in bar, coil, extrusion, plate, profile, rod, sheet, tube. Custom sizes are converted from billet, and we can provide saw cut, waterjet or near net blanks so material arrives closer to your finished part.
What is the UNS or equivalent designation for 5454?
5454 is designated UNS A95454. If your drawing calls out an obsolete or foreign designation we can cross reference it and confirm the equivalent before you order.
What specifications can 5454 be supplied to?
Commonly ordered specifications include ASTM B209, ASTM B221, UNS A95454. Material is released to the specification and condition on your purchase order, with mill test reports supplied as standard.
What conditions can 5454 be ordered in?
We can supply O, H32. If our stock is not already in the condition you need, we can quote it with the heat treatment performed before shipment.
Can you cut 5454 to size?
Yes. Saw cutting, waterjet, laser and shearing are available, along with trepanning, gun drilling, lathe turning and CNC machining, so you can order blanks or rough machined pieces rather than full lengths.
Do you provide test reports and additional testing on 5454?
Every order ships with mill test reports and heat traceability. If your print calls for ultrasonic inspection, penetrant dye, magnetic particle, chemical assay, micrography, hardness or mechanical testing and our stock does not already carry it, we can quote the material with that work performed.
Can 5454 be supplied to DFARS domestic melt requirements?
Tell us at quote stage if the order is DFARS or domestic melt restricted and we will confirm availability against that requirement before you commit.
What do you need to quote 5454?
Grade, form, dimensions, quantity, specification and condition, plus any testing or certification requirements and the date you need it. Send a drawing if you have one. Quotes are typically ready within 24 hours.
How does 5454 compare with 5456?
Higher magnesium and strength, restricted from sustained service above about 150F.
