CORROSION RESISTANCE:
- Engineered to endure corrosive challenges better than any other standard hardenable stainless steels on the market.
- Performance comparable to Alloy 304 across most environmental media.
- Exhibits superior corrosion resistance in chemical, petroleum, dairy, and food processing industries.
- May experience crevice or pitting corrosion if exposed to stagnant sea water for extended durations.
WELDABILITY:
- Easily welded using most common fusion and resistance techniques.
- Not recommended for oxyacetylene welding due to incompatibility.
- Typically, no pre-heating is necessary before welding.
- Maintain inter-pass temperature below 248°F to ensure weld integrity.
- Achieve superior toughness in welds post-complete heat treatment.
ELEVATED TEMPERATURE USE:
- Displays exceptional oxidation resistance up to approximately 1100°F.
- Prolonged exposure to high temperatures may reduce toughness in precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- For forging, uniformly heat the alloy to 2150-2200°F and hold for half an hour per inch of thickness.
- Ideal hot forming temperature range is 650-900°F while the steel retains its austenitic phase.
- Re-heat treat forgings at 1875-1925°F to optimize for hardening processes.
- Cool forgings below 90°F to achieve optimal grain refinement.
PROCESSING - COLD FORMING:
- Alloy 17-4 is suitable for mild operations in its annealed (solution-treated) state due to inherent hardness.
- For severe cold working, heat treat to condition H1150 to prevent cracking.
- A bend radius exceeding 7T is often necessary.
- Re-aging at precipitation-hardening temperatures post-cold forming enhances stress corrosion resistance.
MACHINABILITY:
- Machinable in both solution-treated and precipitation-hardened conditions.
Mechanical Properties
- Type 17-4PH stainless steel boasts exceptional mechanical properties, making it the ideal choice for applications demanding high strength, hardness, and corrosion resistance while being more cost-effective than many high-nickel non-ferrous alloys.
