QuesTek Innovations LLC has introduced a stainless steel composition for powder bed fusion AM for use either in the as-printed condition or with a single low-temperature heat treatment. This allows for production of complex, high-strength stainless parts via AM, comparable to wrought 17-4 PH, but without the need for cryogenic processing or high-temperature heat treatment.

Two feedstock options are available: QT 17-4 for use in the direct-aged condition and QT 17-4+ for use in the as-printed condition. They can be used in a variety of industries, including aerospace, defense, medical, chemical processing, and energy.
