17-4PH Stainless Steel Sta
metal17-4PH stainless steel in the Sta (stress-relieved annealed) condition is a precipitation-hardening martensitic stainless steel providing moderate strength with improved toughness and ductility, typically used in aerospace and defense applications requiring good corrosion resistance and machinability. This condition offers a balance between strength retention and dimensional stability for parts requiring stress relief after machining or forming.

Quality & Standards
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.
