ASTM A335 P5 vs P9
ASTM A335 P5
- • Contains roughly 5% Chromium and 0.5% Molybdenum.
- • Ideal for general high-temperature applications and standard refinery fluid transport.
- • More cost-effective than P9 for intermediate temperature ranges.
ASTM A335 P9
- • Contains roughly 9% Chromium and 1% Molybdenum.
- • Offers significantly higher resistance to oxidation and corrosion at extreme temperatures.
- • Used in more aggressive thermal environments and harsher chemical processing.
