FAQ
Q1: Can 17-4 PH stainless steel be welded?
A1: Yes, but it should be welded in the solution-annealed condition to avoid cracking. Post-weld heat treatment is recommended to restore strength.
Q2: What heat treatments are available?
A2: H900, H1025, H1075, H1150; each offers different strength and hardness levels for application-specific needs.
Q3: Is 17-4 PH corrosion-resistant?
A3: It has moderate corrosion resistance, superior to 304 but lower than 316 stainless steel. Suitable for mildly corrosive environments.
Q4: Can it be used in marine environments?
A4: Yes, for moderately corrosive marine environments. For high chloride exposure, consider duplex or super duplex stainless steels.
Q5: What forms does it come in?
A5: Sheets, plates, bars, tubes, pipes, and wires.
Q6: Can it be polished to a mirror finish?
A6: Yes, it can be polished to both brushed and mirror finishes for aesthetic and functional applications.
Q7: What industries commonly use 17-4 PH?
A7: Aerospace, chemical, petrochemical, marine, tooling, and medical device industries.
