17-4PH SS (SLM, H900)
Verifiedmetal17-4PH is a precipitation-hardening stainless steel optimized for additive manufacturing via selective laser melting (SLM), with H900 heat treatment applied post-build to achieve peak strength and hardness. This material combines corrosion resistance typical of stainless steels with the high strength-to-weight ratio needed for aerospace and defense applications where complex geometries and minimal material waste are critical; engineers select it when traditional wrought 17-4PH cannot economically produce the required part geometry or when the design benefits from direct AM fabrication.

Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
