I have a gas oven stove that can go up to 550°F (~287°C), with also a gas broiler. If I place a muffin pan on the top or second top rack, under the broiler, after preheating the oven at its highest setting, what sort of temperatures might the muffin pan reach?
The end goal's to make some Portuguese egg tarts and I hear that generally it should be cooked as high as the oven can go, so I'm wondering what temperatures the muffin pan needs to tolerate.

Tins for pastéis de nata are typically made of galvanized steel or aluminum, without coating. In commercial bakeries it is also common to see disposable tins made with aluminum foil.
You can use a muffin tin made from the same materials: uncoated galvanized steel or aluminum
All recipes for that I've ever seen ask for a minimum temperature of 250°C (or as far as your oven can go, if it goes above that, which many ovens nowadays won't be able to go too far above it), so you can take 250 as a ballpark temperature for choosing your muffin tins
Use the broiler to finish them and get the charred spots after your pastéis are cooked (usually 25 minutes at 250 would do)
