Elevated Temperature Use and Heat Treatment

17-4PH stainless steel provides excellent oxidation resistance up to about 1100°F. It performs reliably in service conditions between 600°F and 800°F. However, long-term exposure to high temperatures may reduce toughness, especially in precipitation-hardened conditions.

Processing – Hot Forming

For forging, heat the steel evenly to 2150-2200°F and hold for 30 minutes per inch of thickness. Optimal hot forming occurs at 650-900°F, when the material remains austenitic. After forging, re-heat treat at 1875-1925°F to prepare the steel for hardening. Finally, cool the forgings below 90°F to refine the grain structure.

Processing – Cold Forming

In its annealed (solution-treated) state, 17-4PH stainless steel is hard, which limits severe cold forming. For more demanding cold work, first treat the material to condition H1150 to help prevent cracking. Bending often requires a radius larger than 7T. After cold forming, re-aging at the standard precipitation-hardening temperature can improve stress corrosion resistance.

MACHINABILITY:

• Can be machined in both solution-treated and precipitation-hardening conditions.

Mechanical Properties

17-4PH stainless steel offers excellent mechanical properties that make it ideal for applications needing high strength, hardness, and corrosion resistance. Compared to many high-nickel, non-ferrous alloys, 17-4PH stainless steel often provides a more cost-effective solution without compromising performance.

Heat Treatment

Heat treatment is a critical process for achieving the desired mechanical properties and corrosion resistance in 17-4 stainless steel rods. This process involves heating the steel to specific temperatures and then cooling it to develop the required microstructure. Various methods, such as annealing, hardening, and tempering, are employed to tailor the material’s properties.

For instance, solution treating at temperatures ranging from 900°F to 1150°F for one to four hours can help achieve a martensitic structure, providing high strength and moderate corrosion resistance. Alternatively, aging at temperatures between 1050°C and 760°C for two to four hours can result in a precipitation-hardened structure, offering both high strength and excellent corrosion resistance. These heat treatment processes are essential for enhancing the toughness, strength, and overall performance of 17-4PH stainless steel, making it suitable for demanding applications.
