CORROSION RESISTANCE:
- Our High Strength 17-4 pH Stainless Steel Round Bar boasts superior resistance to corrosive attacks, surpassing any standard hardenable stainless steels.
- It offers corrosion resistance comparable to Alloy 304 across most media.
- Ideal for use in chemical, petroleum, dairy, and food process industries due to its reliable corrosion resistance.
- However, prolonged exposure to stagnant sea water may lead to crevice or pitting attacks.
WELDABILITY:
- Our product can be successfully welded using most common fusion and resistance methods, ensuring robust and reliable joins.
- Note that oxyacetylene welding is not recommended for this material.
- Typically, there is no need for pre-heating before welding.
- Maintain an inter-pass temperature below 248°F for optimal results.
- Achieve better toughness in the weld with a complete heat treatment process.
ELEVATED TEMPERATURE USE:
- Exhibits excellent oxidation resistance at temperatures up to approximately 1100°F.
- Be aware that long-term exposure to high temperatures may reduce toughness in the precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- To forge, heat uniformly to 2150-2200°F and maintain temperature for half an hour per inch of material.
- The preferred hot forming temperature range is 650-900°F, where the steel maintains its austenitic structure.
- For optimal hardening, re-heat treat forgings at 1875-1925°F.
- Cool forgings below 90°F to achieve grain refinement for enhanced properties.
PROCESSING - COLD FORMING:
- Alloy 17-4 is suitable for mild operations when in the annealed (solution treated) condition due to its inherent hardness.
- For severe cold working, heat treat the material to condition H1150 to prevent cracking.
- A bend radius greater than 7T is often necessary for effective forming.
- Post cold forming, re-aging at the precipitation-hardening temperature is recommended to enhance stress corrosion resistance.
MACHINABILITY:
- The alloy can be effectively machined in both solution-treated and precipitation-hardened conditions.
Mechanical Properties
- Type 17-4PH stainless steel offers exceptional mechanical properties, making it ideal for applications demanding high strength, hardness, and corrosion resistance. It is also a cost-effective alternative to many high-nickel non-ferrous alloys.
