CORROSION RESISTANCE:
- This material exhibits superior resistance to corrosive environments, outperforming any standard hardenable stainless steel.
- Its corrosion resistance is comparable to that of Alloy 304 in most media.
- Ideal for use in chemical, petroleum, dairy, and food processing industries.
- However, it may be susceptible to crevice or pitting attack if exposed to stagnant seawater for prolonged periods.
WELDABILITY:
- Can be effectively welded using most common fusion and resistance techniques.
- Not recommended for oxyacetylene welding.
- Typically, pre-heating is unnecessary.
- Ensure inter-pass temperatures do not exceed 248°F.
- Post-welding heat treatment significantly enhances toughness.
ELEVATED TEMPERATURE USE:
- Exhibits excellent oxidation resistance up to approximately 1100°F.
- Prolonged exposure to high temperatures may decrease toughness in precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- For forging, heat uniformly to 2150-2200°F and maintain for half an hour per inch of thickness.
- The optimal temperature range for hot forming is 650-900°F when the steel is austenitic.
- To optimize hardening operations, re-heat treat forgings at 1875-1925°F.
- Cool forgings below 90°F to ensure refined grain structure.
PROCESSING - COLD FORMING:
- Alloy 17-4 is best suited for mild operations as it is hard in the annealed condition.
- For severe cold working, heat treat to condition H1150 to prevent cracking.
- A bend radius greater than 7T is often necessary.
- Post cold forming, re-aging at the precipitation-hardening temperature is recommended to improve stress corrosion resistance.
MACHINABILITY:
- This alloy can be machined in both solution-treated and precipitation-hardened states.
Mechanical Properties
- Type 17-4PH stainless steel boasts excellent mechanical properties. It is an exceptional choice for applications requiring high strength, hardness, and corrosion resistance while being more cost-effective than many high-nickel, non-ferrous alloys.
