Printed properties

How the printed metal performs

Carpenter does not publish tensile data on the PowderRange 17-4 datasheet. Its higher nitrogen can stop full transformation to martensite, giving slightly lower properties than 17-4 AR; for typical wrought 17-4 properties Carpenter recommends 17-4 AR, whose data is on its page.

Heat treatment

Carpenter datasheet, process guidance

  • Stress relief: 677 °C (1250 °F), 1 hour per inch of thickness, minimum 2 hours, up to 4 hours.
  • Homogenize to reduce anisotropy: 1093 °C (2000 °F) for 1 hour, air cool. Not needed if you HIP.
  • HIP to close porosity: at least 100 MPa (14.5 ksi) at about 1141 °C (2087 °F) for about 240 minutes in argon.
  • Solution anneal per ASTM A564: 1038 °C (1900 °F) for 0.5 hour, cool below 32 °C (90 °F). Then age, for example H900: 482 °C (900 °F) for 1 hour, air cool.
  • Carpenter advises against using the solution-annealed condition without aging, because of stress-corrosion cracking.
  • Because of its higher nitrogen, PowderRange 17-4 may not transform fully to martensite during heat treatment.

Common questions

Don't see yours? Email [email protected] — NDA on request.

What is PowderRange 17-4 stainless steel powder?
PowderRange 17-4 stainless steel powder is a martensitic precipitation-hardening stainless steel powder from Carpenter Additive, vacuum induction melted and nitrogen gas atomized. It combines good strength, toughness and hardness with corrosion resistance up to 316 °C (600 °F), and it is age-hardened with a single low-temperature treatment. Carpenter lists surgical instruments, valves and fittings, pumps and impellers, manifolds, chemical processing equipment and tooling as typical uses.
What is the difference between PowderRange 17-4 and 17-4 AR?
PowderRange 17-4 is nitrogen gas atomized and allows up to 0.10% nitrogen. Carpenter notes that this higher nitrogen can stop full transformation to martensite during heat treatment, which gives slightly lower properties than 17-4 AR. PowderRange 17-4 AR is argon gas atomized with nitrogen held to 0.030%, and Carpenter recommends it when typical cast or wrought 17-4 properties are required. Both are listed in the table at the top of this page.
How do I heat treat 17-4 after printing?
Carpenter's guidance: stress relieve at 677 °C (1250 °F) for 1 hour per inch of thickness, then homogenize at 1093 °C (2000 °F) for 1 hour, or HIP at about 1141 °C (2087 °F) and at least 100 MPa for about 240 minutes. Next, solution anneal at 1038 °C (1900 °F) for 30 minutes, cool below 32 °C (90 °F), and age, for example at 482 °C (900 °F) for 1 hour (H900). Carpenter advises against using the solution-annealed condition without aging because of the risk of stress-corrosion cracking.
How corrosion-resistant is 17-4 stainless steel?
PowderRange 17-4 offers good general corrosion resistance. Carpenter rates it, from wrought experience, as excellent in humidity, good in nitric acid and salt spray, moderate in acetic acid and sodium hydroxide, and restricted in sea water, sulfuric and phosphoric acids and sour oil and gas. It resists corrosion up to 316 °C (600 °F). Additively manufactured material can behave differently, so Carpenter recommends corrosion testing for your application.
Does 17-4 stainless steel powder come with a certificate of analysis?
Yes. Every order of PowderRange 17-4 stainless steel powder ships with Carpenter Additive's certificate of analysis for the lot you receive. It lists chemistry, particle size distribution (D10, D50, D90), flow and apparent density, with the lot number for traceability. Carpenter states that its powder testing meets Nadcap Materials Testing and ISO/IEC 17025 chemical requirements. If your quality team needs to review a recent certificate before you order, ask us and we will send one.
How fast does 17-4 stainless steel powder ship, and how can I pay?
PowderRange 17-4 stainless steel powder is out of stock at the moment, and the availability column in the table at the top of this page always shows the current status. If your build cannot wait, the same table lists PowderRange 15-5PH, a stronger precipitation-hardening stainless steel, and CNPC Powder 17-4PH, which CNPC confirms is nitrogen gas atomized. Every option in that table has a published price, so you can compare and order in one place, or email [email protected] and we will tell you what can ship soonest.
Can I reuse unfused 17-4 stainless steel powder?
Many teams sieve and reuse unfused 17-4 stainless steel powder powder. How many reuse cycles you allow is part of your own qualification, so track particle size distribution and oxygen against your specification as the powder ages. Sieve before loading and after every build, keep recovered powder in a sealed container, and use an ATEX-rated vacuum for clean-up. We sell the ATO Sieve and Delfin powder vacuums shown on this page.
