Metals in cooking appliances

Hello,

I'm looking for examples of metals used to construct cooking appliances:

1. What kind of metal is used to design the outer shell of industrial cooking appliances? It is some sort of sheet-like metal, that i think is also used to make industrial cooking tables.

1. What would be the metal that covers the inside of an oven? I'm looking for the name of a metal which has high capacity, and which is commonly used in ovens.

thanks. btw, i'm a patent agent, and i just want the name of such metals for indicative purposes, to include in a patent application i'm working on right now. (component A is made of a metal which can sustain high temperatures and which has high heat capacity, for example ______ )
