Using A350/LF2 instead of A105

[ezat2007]

is there a limitation to use A350/LF2 instead of A105 forged material, there is no low temp. condition the working temp. assumed to be max. 200 C and the impact test is not required.
also as i know A350/LF2 can used from -46C to 345C nd A105 can used from -29C to 427C is this information is documented and if please advice.

Check your construction code you´ll find your answers there, you´ll need the materials class (1 or 2).

A350LF2 is requonized better than A105.
In case of low temperature you need to check if class 1 or 2 is required (class 1 impact test @-46°C & class 2 impact test @-18°C).
Many informations are available in each specification in ASME II A.
For limitation in high temperature check in table 1A in ASME II D.
