(1) kind of corrosion mechanism investigated * Using low ferrite grade

The alloy is not really resistant to localized corrosion in chloride containing
solutions. Pitting may occur even at low temperature (5-10°C – 41-50°F).
The alloy is very prone to stress corrosion cracking in chloride containing solution
when temperature is higher than 50°C ( 122°F).
