17-4 PH Stainless Steel Bar
17-4 PH Stainless Steel Bar is a highly versatile and widely used precipitation-hardening alloy used in various aerospace, nuclear energy, and chemical processing applications. One of the original “PH” (precipitation hardening) grades, 17-4 delivers a combination of oxidation and corrosion resistance, along with high strength, toughness, and the capability of achieving numerous quality mechanical properties through heat treating at various temperature ranges. 17-4 can be machined in the annealed condition and in the heat treated state. Maximum toughness is achieved by aging at 1150°F, while maximum strength is attained through aging at 900°F.
