Iron Based Metal Powders

What to know before you buy

This collection covers iron based metal powders made for additive manufacturing (3D printing), all under the MSE PRO brand. Current alloys include 17-4PH, a precipitation hardening stainless steel, 304L stainless steel, a low carbon austenitic grade, and pure iron (Fe).

Choose the alloy by what the printed part needs. 17-4PH is used where strength and hardness matter, and it can be heat treated after printing to adjust those properties. 304L suits corrosion resistant parts and general stainless work, and its low carbon content helps limit sensitization during heat cycles. Pure iron suits studies of magnetic behavior and sintering, and serves as a base for alloy development.

Particle size distribution needs to match the process, since laser powder bed fusion, binder jetting and directed energy deposition each favor different size ranges. Compare the size options on each listing with your printer maker's powder spec. For examples of where these powders end up, read Diverse Applications of Additive Manufacturing Metal Powders.

Frequently Asked Questions

Should I choose 17-4PH, 304L or pure iron powder?

Pick 17-4PH for printed parts that need high strength and hardness after heat treatment, such as tooling inserts and brackets. Pick 304L for corrosion resistant parts, fluid handling components and general stainless prints. Pick pure iron for soft magnetic studies, sintering research or as a base powder for blending your own alloys.

What particle size do I need?

That depends on your printing process and machine. Laser powder bed fusion generally uses a finer cut than directed energy deposition, and binder jetting has its own range. Check your printer maker's powder specification, then compare it with the size options listed on each product page. If none match, ask for a custom particle size through the quote request page.

Can these powders be used for work other than 3D printing?

Yes. They are listed for additive manufacturing, but labs also use iron based powders in press and sinter studies, metal injection molding trials, coating research and powder characterization. Confirm that the listed particle size suits your method before ordering, or request a different size range for that work.

Can I order a custom alloy or particle size?

Yes. Send the target chemistry, size distribution and quantity through the quote request page. If you are matching an existing material, include its grade name or a data sheet so the request is clear.

How do I order larger quantities for several builds?

For powder in larger amounts, or several alloys in one order, use the bulk order request form. List the alloy, particle size range and total mass for each item, and mention the printer or process you use so the size range can be checked against it.
