CS Tubes A179 N

[Aodwan]

Our client asked us to provide SA179 Normalized CS tubes, I have checked in ASME Codes but could not find Normalization temp. for this grade.

Inside section of heat treatment of SA179, it says tubes shall be heat treated at Temp 650 deg C or higher, but not mentioned anything for Normalization temp., is it more than this ?

( I have searched similar old thread ex. (thread794-330949) so it depicts that no where its mentioned in ASME codes) Any suggestions.

Sorry if I missed something inside ASME Codes.

The current ASME SA 179 does not require normalization as a heat treatment. All that is required is tempering at a minimum of 1250 deg F (650 deg C) after cold draw, see below

6. Heat Treatment
6.1 Tubes shall be heat treated after the final cold draw pass
at a temperature of 1200°F [650°C] or higher.

As written 6.1 does not preclude normalizing. Normalizing temp would be approximately 1650F.
