ELEVATED TEMPERATURE USE:
- Exhibits excellent resistance to oxidation at temperatures up to 1100°F.
- Prolonged exposure to high temperatures can reduce toughness in precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- For forging, heat uniformly to 2150 / 2200°F and hold for half an hour per inch of thickness.
- Optimal hot forming temperature range is 650-900°F, while the material remains austenitic.
- Re-heat treat forgings at 1875-1925°F to ensure optimal hardening conditions.
- Cool forgings to below 90°F to achieve grain refinement and superior quality.
PROCESSING - COLD FORMING:
- Alloy 17-4 is suitable for mild operations due to its hardness in the annealed state.
- For severe cold working, heat treat to condition H1150 to prevent cracking.
- Bend radii exceeding 7T are often necessary for best results.
- Post cold forming, re-age at the precipitation-hardening temperature to enhance stress corrosion resistance.
MACHINABILITY:
- Machinable in both solution-treated and precipitation-hardened conditions, making it versatile for various applications.
Mechanical Properties
- Type 17-4PH stainless steel offers exceptional mechanical properties, combining high strength, hardness, and corrosion resistance, making it a cost-effective alternative to high nickel non-ferrous alloys.
