CORROSION RESISTANCE :

The alloy has only limited resistance to localized corrosion in chloride containing solutions. Pitting may occur even at low temperature (5 - 10°C / 41 - 50°F).
The alloy may suffer from stress corrosion cracking in chloride containing solution when temperature is higher than 50°C (122°F).

APPLICATIONS :

UR™ 304L* is corrosion resistant in :
• Nitric solution, up to 55% weight, up to 80°C (176°F) (low ferrite)
• Most of diluted organic acids at moderate temperatures
• Most of food and pharmaceutical products
• Pure phosphoric acid
  - whatever concentration in cold solution
  - up to 10% diluted hot solution
Sulphuric or fluoridric acid traces increase the corrosion
• Caustic solutions free of chlorides or fluorides at medium temperatures
• Food processing industry (excluding Cl- containing media)
