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 reviewReview chemical exposure and the required annealed condition.State the heat treatment and any sour-service requirements separately.
