PowderRange 17-4 stainless steel is a martensitic precipitation/age-hardening stainless steel offering high strength and hardness, along with excellent corrosion resistance, up to 600°F (316°C). It has good fabricating characteristics and can be age-hardened by a single-step, low-temperature treatment, which can be chosen to achieve specific strength and toughness combinations. Due to this balanced combination of performance and ease of use in AM, PowderRange 17-4 for additive manufacturing has been used for a wide variety of applications, including rapid tooling functional components in nearly every market.

IMPORTANT NOTE: The following 4-level rating scale (Excellent, Good, Moderate, Restricted) is intended for comparative purposes only and is derived from experiences with wrought product. Additive manufactured material may perform differently; corrosion testing is recommended. Factors that affect corrosion resistance include temperature, concentration, pH, impurities, aeration, velocity, crevices, deposits, metallurgical condition, stress, surface finish, and dissimilar metal contact.

The mechanical and physical properties of any additively-manufactured
material are strongly dependent on the processing conditions used to
produce the final part. Significantly differing properties can be obtained by
utilizing different equipment, different process parameters, different build
rates and different geometries. The properties listed are intended as a
guide only and should not be used as design data.
The information and data presented herein are typical or average values
and are not a guarantee of maximum or minimum values. Applications
specifically suggested for material described herein are made solely for the
purpose of illustration to enable the reader to make his/her own evaluation
and are not intended as warranties, either express or implied, of fitness for
these or other purposes. There is no representation that the recipient of
