What is the basis for improving the impact performance of steel plates in pressure vessel design?

I seek advice from experts: what is the basis for improving the impact properties of steel plates in pressure vessel design? For a certain device, the design temperature ranges from -48°C to 65°C, the medium used is propylene, and the operating pressure is 2.0 MPa; 09MnNiDR steel plates are used – by how much should the impact energy of these steel plates be increased?
First, consider the standard specifications, then the operating temperature, taking into account the influence of ambient temperature.
