Using TL071 at 455 kHz
My question is can I use this device for making a 455 kHz signal
amplifier in practice as the simulation shows about 18dB gain at
400KHz?

The 18 dB of gain you get roughly tallies with the open loop response from the data sheet so, you can amplify the 455 kHz signal but if you are expecting a clean distortion free output it might not be quite like that because the op-amp is running pretty close to to its top-end of the spectrum and op-amps rely on a lot of &quot;spare&quot; open-loop gain for a &quot;high fidelity&quot; signal amplification.
