Does the stainless steel grill will hold in the air fryer?

You can. Any container with high heat resistance will do. Air fryer An air fryer uses air instead of hot oil in a frying pan and is heated by convection, similar to hot wind from the sun, which creates a rapid circulation of heat in a closed pan to cook food. The hot air also blows away moisture from the surface of the food, allowing the ingredients to have a similar effect of frying without needing to roll in oil.
Air fryers use high-speed air circulation technology to make delicious French fries with up to 80% less fat than traditional fryers. The unique combination of fast-circulating hot air and oven components enables a fast and convenient way to fry all kinds of delicious food, snacks, seafood, etc.

The stainless steel basin can hold the air fryer, because the temperature of the air fryer is up to 220 degrees, and the stainless steel can be put into it.
