This range may be reduced by the selected process connection. The pressure rating (PN) specified on
the flanges refers to a reference temperature of 20 °C, for ASME flanges 100 °F. Pay attention to
pressure-temperature dependencies.
Please refer to the following standards for the pressure values permitted for higher temperatures:
• EN 1092-1: 2001 Tab. 18
With regard to their temperature stability properties, the materials 1.4435 and 1.4404 are grouped
under 13E0 in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.
