CORROSION RESISTANCE:
- Our stainless steel exhibits superior corrosion resistance, surpassing standard hardenable stainless steels in durability and performance.
- Performance comparable to Alloy 304 in most types of corrosive environments.
- Ideal for use in chemical, petroleum, dairy, and food processing industries due to its robust corrosion resistance.
- Caution: Extended exposure to stagnant seawater may lead to crevice or pitting corrosion.
WELDABILITY:
- Capable of being welded using most common fusion and resistance welding techniques.
- It is not recommended for oxyacetylene welding applications.
- Typically does not require pre-heating before welding.
- Maintaining an inter-pass temperature below 248°F is crucial.
- Achieve superior weld toughness through a comprehensive heat treatment process.
ELEVATED TEMPERATURE USE:
- Displays excellent oxidation resistance at temperatures up to 1100°F.
- Note: Prolonged exposure to high temperatures can diminish toughness in precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- For forging, uniformly heat to 2150-2200°F and maintain for half an hour per inch of thickness.
- The optimal temperature range for hot forming is between 650-900°F while the steel is still in its austenitic phase.
- To ensure optimal hardening, re-heat treat forgings at 1875-1925°F.
- Cool forgings to below 90°F to achieve grain refinement.
PROCESSING - COLD FORMING:
- Cold forming operations should be mild due to the material's hardness in the annealed condition.
- For more severe cold working, heat treatment to condition H1150 is recommended to avoid cracking.
- A bend radius exceeding 7T is generally required for cold forming.
- Re-aging at the precipitation-hardening temperature after cold forming enhances stress corrosion resistance.
MACHINABILITY:
- This alloy is machinable under both solution-treated and precipitation-hardening conditions.
Mechanical Properties
- Type 17-4PH stainless steel offers superior mechanical properties, combining high strength, hardness, and corrosion resistance, making it a cost-effective alternative to high-nickel non-ferrous alloys for demanding applications.
