CORROSION RESISTANCE:
- Excels in resisting corrosive attacks, surpassing standard hardenable stainless steels.
- Comparable to Alloy 304 in most environmental conditions.
- Highly resistant to corrosion in chemical, petroleum, dairy, and food processing industries.
- Prone to crevice or pitting attacks if exposed to stagnant seawater for extended periods.
WELDABILITY:
- Easily weldable using most common fusion and resistance techniques.
- Not recommended for oxyacetylene welding.
- Generally, pre-heating is not necessary.
- Inter-pass temperature should be strictly limited to 248°F.
- Enhanced toughness can be achieved in welds with complete heat treatment.
ELEVATED TEMPERATURE USE:
- Demonstrates excellent oxidation resistance up to approximately 1100°F.
- Prolonged exposure to high temperatures may reduce toughness in precipitation-hardened conditions.
PROCESSING - HOT FORMING:
- For forging, heat uniformly to 2150-2200°F and maintain for half an hour per inch.
- Optimal hot forming temperature range is 650-900°F while the steel remains austenitic.
- For ideal hardening, re-heat treat forgings at temperatures between 1875-1925°F.
- Cool to below 90°F to ensure proper grain refinement.
PROCESSING - COLD FORMING:
- Suitable for mild operations; in the annealed state, the material is hard.
- For severe cold working, heat treat to condition H1150 to prevent cracking.
- Bend radius exceeding 7T is often necessary.
- Re-aging at the precipitation-hardening temperature is recommended to enhance stress corrosion resistance post cold forming.
MACHINABILITY:
- Machinable in both solution-treated and precipitation-hardening states.
