Please advise the standard carbon steel for -60 Celsius. As I know LF2 can be used there, but supplier can guarantee only -50 Celsius.
So advise, is it possible to use LF2 or it's better to use LF3 (down to -100 Celsius).
If your spec calls for that temperature, and the references say the metal cannot be guaranteed to that low a temperature, why would you think we would over-ride the supplier?
