CORROSION RESISTANCE:
- Demonstrates superior resistance to corrosive attacks, surpassing any standard hardenable stainless steels.
- Performs comparably to Alloy 304 across most media applications.
- Exhibits robust corrosion resistance in specific chemical, petroleum, dairy, and food processing industries.
- May experience crevice or pitting corrosion if exposed to stagnant seawater for prolonged periods.
WELDABILITY:
- Successfully weldable through most conventional fusion and resistance techniques.
- Not recommended for oxyacetylene welding due to material properties.
- Typically, pre-heating is unnecessary for welding.
- Ensure inter-pass temperatures do not exceed 248°F to maintain material integrity.
- Enhanced toughness can be achieved in welds following a comprehensive heat treatment process.
ELEVATED TEMPERATURE USE:
- Shows excellent oxidation resistance up to approximately 1100°F.
- Extended exposure to high temperatures may reduce toughness in precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- For forging, uniformly heat to 2150-2200°F and hold for 30 minutes per inch of thickness.
- Ideal temperature range for hot forming is between 650-900°F while maintaining an austenitic structure.
- To optimize hardening, forgings should be re-heat treated at 1875-1925°F.
- Cool down forgings to below 90°F to achieve grain refinement.
PROCESSING - COLD FORMING:
- Given its hardness in the annealed state, Alloy 17-4 is suited for mild cold forming operations.
- For more severe cold working, heat treatment to condition H1150 is recommended to prevent cracking.
- A bend radius greater than 7T is typically necessary for cold forming.
- Re-aging at the precipitation-hardening temperature post-cold forming improves stress corrosion resistance.
MACHINABILITY:
- Capable of being machined in both solution-treated and precipitation-hardening states.
Mechanical Properties
- Type 17-4PH stainless steel offers exceptional mechanical properties, making it ideal for applications requiring high strength, hardness, and corrosion resistance. It is also more cost-effective compared to many high-nickel non-ferrous alloys.
