17-4PH H900 Stainless Steel
17-4PH (UNS S17400) is a precipitation-hardening martensitic stainless steel known for its high strength, good corrosion resistance, and excellent mechanical properties up to 600°F (316°C). The H900 temper offers the highest strength levels, making it ideal for aerospace, nuclear, and high-performance industrial applications. It provides corrosion resistance equivalent to 304 or 430 stainless steel in mild environments.
