Temperature & corrosion

Evaluate the medium, concentration, impurities, temperature and loading together. A melting point or oxidation reference is not a safe working-temperature limit.

Service conditions to reviewSpecify the medium and flow conditions, especially for seawater.Confirm the aging condition and susceptibility to cracking in the actual service.
