ELEVATED TEMPERATURE USE:
- Exhibits excellent oxidation resistance 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 maintain for 30 minutes per inch of thickness.
- Optimal hot forming temperature range is 650-900°F, ensuring the steel remains austenitic.
- To optimize hardening, forgings must be re-heat treated at 1875-1925°F.
- Ensure forgings cool below 90°F to achieve grain refinement.
PROCESSING - COLD FORMING:
- Due to its hardness in the annealed state, Alloy 17-4 is suitable only for mild cold forming operations.
- For severe cold working, heat treat to H1150 condition to minimize cracking risks.
- A bend radius greater than 7 times the material thickness is often necessary.
- Post-cold forming, re-aging at precipitation-hardening temperatures is recommended to enhance stress corrosion resistance.
MACHINABILITY:
- This alloy can be effectively machined in both solution-treated and precipitation-hardened conditions.
Mechanical Properties
- Type 17-4PH stainless steel offers exceptional mechanical properties. Ideal for applications where high strength, hardness, and corrosion resistance are critical, it stands out as an economical choice compared to many high nickel non-ferrous alloys.
