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 S32760 explicitly; it is a separate grade from S32750.Confirm section size, solution treatment and the actual corrosion environment.
Temperature-dependent dataNot documented in this referenceNot documented in this reference

Heat treatment

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