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 310H / S31009, product form and condition. Confirm creep design requirements and service atmosphere.
Temperature-dependent dataNot documented in this reference

Heat treatment
