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 reviewCheck oxidizing impurities, particularly ferric or cupric salts.
Temperature-dependent dataNot documented in this reference

Heat treatment

Delivery condition and heat-treatment requirements are agreed for the requested product form and order.
